Has anybody used an Eagle One vertical antenna? (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 looked at their site. There no specs on the antenna I could see.

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. 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

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?

K7JLJ

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

Jim, I watched the video. Have you used the MPAS and what was your experience, given they are similar designs?

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.

K7JLJ

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:

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

We've more than 20 different purchasing locations all around the globe: (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!
