Title: Eagle One Portable Vertical HF Antenna
Post by: pea on March 30, 2015, 11:24:59 AM

Has anybody used an Eagle One vertical antenna? (http://www.w8afx.com (http://www.w8afx.com))

It gets a lot of good comments and looks like it would be an easy grab-and-go antenna.

Anyone here ever used one??

Sure have used one and it works fairly well as a portable vertical.  On 40 meters it can be used without a tuner but needs one an all the other bands.  I use mine with an Icom AH-4 autotuner at the feed point and get 10 thru 80 meter operation.  In fact, I gave W8AFX the idea to use the fiberglas Jackite pole for the antenna when he had an all aluminum antenna break in a windstorm.  For what it is, its a simple antenna that does work.  Not the most efficient antenna in the world, but any antenna is better than no antenna, and one that is 31' tall and breaks down into a package only 44 inches long makes it great for portable or field day operations !

I'm looking at getting this, 6-80 Meter Alpha Vertical https://amateurradiostore.com/index.php?main_page=product_info&cPath=2&products_id=161 (https://amateurradiostore.com/index.php?main_page=product_info&cPath=2&products_id=161%20%7C%206-80%20Meter%20Alpha%20Vertical). The product page explains the difference between it and the EZ military. It's only 13'. A local ham operator uses this on an apartment balcony with exceptional results. I have an HOA and do some camping, so the ease of set up and break down is an attractive feature.

I see they're also having a sale on their Gold version, basically all the attachments except the mobile conversion mount, https://amateurradiostore.com/index.php?main_page=product_info&cPath=2&products_id=288 (https://amateurradiostore.com/index.php?main_page=product_info&cPath=2&products_id=288)

I can recommend the MPAS system, I was looking at the  EZ Mil before I went with the Chameleon system.

Jim, what were your reasons for going with the MPAS? It looks like the cost is comparable. I understand the versatlity. Just thinking out loud, wouldn't an Alpha Vertical bent over similar to a military whip antenna become NVIS? The Alpha Vertical can also be configured as a mobile installation. I don't see a tripod option, although I'm currently using a repurposed worklight tripod for UHF/VHF portable operations. The Alpha Vertical has a tripod integrated into the design.

Reasoning was the MPAS was tried and true already, Chameleon has perfect CS, and the only person I found online that said it works great is a guy that does his QSOs at the beach and is a sponsor of them (which he doesn't say outright) so I believed it to be too good of a thing.  Also I believe it's using electronics for a match as well as the company says it's a poor choice for QRP which is all I use.

One advantage I see for the Chameleon is it's 6m to 160m. Alpha Vertical does down to 80m.

However, I'm still trying to follow your logic. I already mentioned a local ham has an Alpha Vertical he uses on his balcony with exceptional results. Both of these antennas seem to be designed similarly, with an aluminum whip held together with shock cords, and an antenna matcher. They're similarly priced. Why would one be a poor choice for QRP and one not? Both require a tuner. What do you mean by using electronics for a match? Isn't that what a tuner does?

The QRP advice was from the owner of EZ Antenna.  It's so inefficient that QRP would suffer was the gist I got.

Keep googling, you'll find it.  Also "videosbymike" is the guy I mentioned before. He's on u tube

Hi -

KK4TTR Asked me to chime in on this. Steve (N0TES) here, from Alpha Antenna. The Chameleon MPAS (and all their other antennas) and Alpha Vertical (or EzMilitary) Gold editions (with tripod+mast) should perform almost identically and the only the only real difference being that Chameleon might cost more, likely comes with less accessories, and claims it does 160M. The Alpha Gold editions "will do" 160 meters as well as the Chameleon's systems, but because there are so much better 160 Meter solutions available, I thought it unfair to the consumer to claim efficient operations on 160 meters.

You can use the Chameleon or Alpha EzMilitary for QRP with really good results. But, as I am a QRP purest, I'd highly recommend looking at the magnetic loop antennas from AlexLoop, Chameleon, or Alpha Antenna. I love the SWR indicator on the Alpha Loop that lights up when SWRs are less than 2:1! I also found that the Alpha Loop is the only one that has combined a light system, that is rated at IP54, and includes a tripod & duffle bag. I should also mention that the Alpha Loop can be mounted on the universal Jaw Mount, which allows the Loop to be placed nearly anywhere that a tripod isn't practical.

The Eagle One is OK, but as others have said, it is too short to maintain efficiencies on lower bands. So, you might consider the 43 foot S9 (S9v43) from http://S9Antennas.com and get the $89 Balun from them or a Balun from 'Balun Designs' to enable multiband capabilities. Also, make sure you inspect each fiberglass section if you buy an Eagle One, or S9 for that matter.

As for the guy in Florida on YouTube, he's an old school cop that found something he believes in; so as part of his hobby, he makes YouTube videos of his equipment...Solar Generators, External Speakers, many rigs, and often of his favorite mode of operation on the beach where he does use the EzMilitary antenna or the 10-40 Meter Coaxial Alpha Loop Antenna. Mike's just a gruff guy who you couldn't pay enough to endorse or stop endorsing a product!!

I am happy to send SurvivalTech Nord from YouTube antennas so that he can test and make a video for all like he was willing to do for Chameleon; if he will accept my invitation to.

If I can help you any further, please feel free to send an email to support@AlphaAntenna.com, visit us at http://AlphaAntenna.com, or call me at 1-888-482-3249 ext 2, or if for an after hours emergency my cell phone is (816) 282-8234.

P.S. Another difference between Alpha Antenna and many other manufacturers, is that we have invested our and our employees families lives to serving you everywhere, which INCLUDES a presence AT HAMFESTS.

Steve, thanks for the response. I just placed an order for an Alpha Vertical Gold. You answered all my questions.

I'll post a review here of the antenna in operation. Can't wait to get it set up. Anything has to be better than the home brew dipole in the attic. Digital modes are passable, but SSB mode is unintelligible on receive. I took the rig to a friends house and the IC-7200 receives as well as his Kenwood, so it has to be the antenna.

Looking at the specs between the Chameleon and Alpha antenna systems, I figured there couldn't be too much difference. The Alpha Vertical Gold or EZ-military Gold offers quite a lot in one package.
Title: Re: Eagle One Portable Vertical HF Antenna
Post by: K7JLJ on January 03, 2016, 05:31:22 PM
Thanks for coming in Steve, I'll forward your offer to him if you haven't already contacted STN.  I'm sure he would love to do a comprehensive comparison.

NCGunDude, I have had nothing but success with it but have had little time on air.  I'll be doing CW Reverse beacon stuff with it later this year to give a better idea of its effectiveness.

I posted on the Google+ so hopefully STN will take EZ up on his offer.

NCGunDude,

this is Carl from Chameleon Antenna. The first thing that a customer is noticing with our products is the manufacturing quality of the unit. Everything is professionally CNC engineered in our Santa Ana (California) shop. We aren't building it in our garage or basement. We're using the same top quality materials that is used by commercial corporations, aerospace engineering companies and various defense/military contractors. We're talking about American stainless steel, anodized 7075 or 6061 aluminum, Delrin, Black Acetal, brass, copper, polypropylene and much more. We aren't using any schedule 40 fitting or sewer piping from Home Depot or Lowes! All our products are identically built and 100% made in USA.

You can see by yourself at the following link:
https://www.dropbox.com/photos/shared_space/3SFzFciaPIMXXGD
(https://www.dropbox.com/photos/shared_space/3SFzFciaPIMXXGD)

We're also focusing our energy and investing most of our manufacturing cost and time into the main antenna components. We do not inflate our prices with bundled peripherals that can be purchased just about everywhere. We've innovative designs and incorporate customers findings in future product upgrades and improvements.

Talking about innovative designs and improvements: Our magnetic loops (CHA F-LOOP and CHA F-LOOP Plus) are currently the best example of it. It's the only portable magnetic loop on the market that can be equipped with a collapsible 1" diameter radiating element which will increase your radiating power more than anything else.

You can read about it here: http://chameleonantenna.com/PORTABLE%20ANTENNA/CHA%20F-LOOP/Chameleon%20F-LOOP.html (http://chameleonantenna.com/PORTABLE%20ANTENNA/CHA%20F-LOOP/Chameleon%20F-LOOP.html)

We've more than 20 different purchasing locations all around the globe: (http://chameleonantenna.com/CONTACT%20US/DEALERS/DEALERS.html (http://chameleonantenna.com/CONTACT%20US/DEALERS/DEALERS.html)).

We're manufacturing a product that would make your transmitted WATT works for you and not the opposite!

Hello Steve, Carl
I've just sent Steve an email.  I would be delighted to do a side-by-side comparison between the EZ Military & MPAS. In fact I'm really surprised we haven't done this sooner. Certainly both antenna systems have their pluses and minuses, but rather than commenting on another manufacturer's products, why not let the numbers paint the picture!?

My idea is to do a video series of a side-by-side comparison.

In the first video, I'll do a comparison of:
- Whats in the package
- Specifications
- Price
- Weight
- Ease of assembly
- Configuration options
- Available accessories

In the second video, I'll cycle incrementally through the bands in real time, using the following tools:
- WSPR
- PSK Reporter
- Reverse Beacon Network
- ...

Using the Yaesu FT-817ND & z817 tuner with an antenna switch between the two systems.
(Don't worry I will place them far enough apart to avoid coupling)
We will start each test at 5 watts, then 2.5 watts, 1 watts, 0.5 watt on each relevant band 160-6M. I'll also repeat this test several times, in a various configurations.

In the last video, we will take both antenna systems out to the field for some winter emcomm training. After that will go through the pluses and minuses of both systems, letting users come to their own conclusions based on the objective information that we give them.

Each portion of the test will be available on the Internet for comparison.

With all that said, I absolutely accept the opportunity to do the side by side comparison.
With kind regards

Julian
STN

NCGunDude,

the MPAS will indeed cover 6M to 160M very well with the provided 60' Polypropylene covered Copper Clad Iron wire and 6M to 80M with the vertical whip. At 80M and 160M any vertical whips of that length will radiate very little power.

Collapsible vertical whips are good for quick COMM on the go where no external supports like trees, masts or fences are available. But when they're available, then try to use the wire as much as possible. You'll transmit more RF power with less input power and get better results.

The HYBRID-MICRO can also be used with your own lengths of wire configurations to create just about anything you want from Windom antennas, to dipoles, skyloops and delta loops! You just need to carry an extra 100' of wire or more (16 to 18 gauge) with you in the field.

You can even build your own 43' vertical with the HYBRID-MICRO:

Hello,

Great plan, and sounds like fun STN! My team and I will prepare send you the Alpha Antenna in its' many deployable form factors; including a) Mobile (MOTO), EzMilitary, Vertical, and JPole (modified dipole/zepp)...and because you will already have all of the universal deployment hardware from Alpha Antenna, I will also send you our Coaxial Alpha Loop that uses the same universal mounts. By universal mounts, I mean that we have merged the Amateur Radio thread count of 3/8 x 24 with the Photography thread count of 1/4 x 20 with our custom machined Top Of Mast Adapter. This part enables hundreds of different and inexpensive mounts from the world of photography to mount either the EzMilitary or the Coaxial Loop!

I think this will be a very fun video series.
I'll reply to your email shortly.

Just wanted to say that the Eagle One is nothing special, secretive, or even new.  Its basically a new way to support the old 30' up and 30' out wire antenna where you hung a 30 to 35' wire in a tree and used and equal length counterpoise wire on the ground.  The Eagle One uses a 33' wire inside a 31' Jackite pole for support and you can use any number of counterpoise or radials wires as you wish.  So its basically a 40 meter quarter wave vertical that will work other bands via a tuner.  The best place for the tuner is at the base of the antenna such as an Icom AH-4 or one of the SGC wire tuners to help eliminate feedline loss.  I used mine with the AH-4 and got 6 thru 80 meter operation with good results.

The Eagle One is basically a 40 meter quarter wave vertical - 33' of wire inside a telescopic fiberglass pole.  With the use of a tuner at the feedpoint (Icom AH-4, SGC-237 etc) it can be used on other bands.  Some folks are using it with a tuner in the shack by adding a 4:1 balun at the feedpoint but that causes a lot of loss in the feedline due to a high swr on the feedline.  By putting a tuner at the feedline the coax is operated in a matched situation and losses are much lower.
