This is an area that absolutely fascinates me.  Thanks.

Also, I just have to chuckle, knowing who the poster is, and seeing him described as a Newbie.

Good coaching, Gil, thanks.  It's assembled by Bienno, which seems to be well thought of.  It is described as having a BMS integrated into it, and they are also providing the charger.  I considered using the power supply to charge the battery, but quickly realized that if the power supply is online, I have AC with which to supply the charger. (Duh).

Woo-hoo!  Thanks, Richard.  I'm struggling a bit in my wish-list for the box.  I'm looking at 30-amp power supplies, and I'd like to dial the voltage a bit, as well as have digital meters for both volts and amps.  In addition, I have  15-AH LiFePo4 12v pack ordered, and I also want to be able to attach to external 12v batteries via something resembling a set of jumper cables.  I'd really like a 3 or 4 position rotary switch to select the power source, but most folks who blog or YouTube about their EMCOMM kits are a little thin on these sorts of details.

PM's coming.  Thanks again.

After a lot of study, agonizing, deciding, undeciding and final, this is IT resolution...

I bought a Yaesu FT-857d, plus a Signalink USB TNC.  These seem to figure prominently in folks' EMCOMM kits.  Glad that decision is behind me.  I plan to build my home station in an audio gear travel case.  (One with wheels and a pull-up handle).  This will allow me to take to the field with the same kit I operate at home.

This gonna be a lot of fun!

Thanks for letting me share.

Antennas / Re: Not happy with Hamtennas

Thanks for the tips, new friends.  D'ye think the chameleon mil and mil ext, coupled with the hybrid micro might save the day?  To reiterate, my interest for this is emcomm portable operation, not mobile.  My home/base antenna will be a G5RV set up in an inverted Vee.  I'm afraid of throwing more money at an insoluble problem.  Frankly, having read all the good reviews of the MFJ-347 mini dipole clamp leads me to believe that reviewers at eham have no clue what they're talking about.  Oh well, I can trim the "stingers" to be resonant for win link stations, or some other edge case.

Otoh, I wonder what hro's return policy is?

Antennas / Not happy with Hamtennas

I was actually in HRO in Atlanta a few weeks back, and asked one of the folks there about the Chameleon "stiff dipole" arrangement using an MPAS as the basis.  He suggested getting an MFJ-347 HF stick mini dipole mount.  It was attractively priced, and I got that, and a pair of a sticks for 40m, and a pair for 75/80m.  NVIS, don'tcha know.

Damn.  The mount itself seems to be beautifully made.  I plugged the 40m Hamtennas in, and tested it with my MFJ-259c antennalyzer.  Min SWR at ~ 6.8mhz.  No real problem there, just shortened the stainless steel whips an equal amount on both sticks.  Got a minimum SWR of 1.5, right in the middle of the 40m band, about 7.145.  Swept the analyzer to the lower edge... SWR 8.8.  Swept to the upper edge of 40m, SWR 10.5.  No integrated antenna tuner is gonna match that.  Sent in the symptoms to MFJ, and called them today for a consult.  Their response was, essentially, "working as designed".  I'm thinking I pissed away a hundred bucks.  This was going to be part of my portable station gear, but I don't see how it will work for that, now.  Guess I'll ditch this, or maybe figure some other use case.

Antennas / Re: Inverted Vee dipole, legs not collinear

Thanks, Gil, and thanks for this forum.  Reading your response, I just want to make sure I understand.  I've seen several blog posts about currently available copies of the military NVIS design, and while they are inverted V's, my concern was that the two legs of my 40m element will form a Vee shape as viewed from above.. Since that's not a concern, I'm ready to get my tilting mast erected.

Thanks again

Antennas / Inverted Vee dipole, legs not collinear
« on: July 19, 2016, 12:55:36 PM »
New friends, I found this,site a few months back, and joined to pose this question:

I am planning to put up a permanent inverted Vee dipole for NVIS operation.  I will not be able to run the two legs in a straight line, more like a shallow Vee (as viewed from above), likely bat 20 degrees off straight.  Is this going to work?  What might be the affect on radiation pattern?  My plans are to used a trapped dipole that will be a full half wave for 40m, and trapped for 80.  Center point should be ~30 ft above the house, with the ends being almost to the roof of my one-storey house, call it ~ 12ft AGL.

TIA...

Hutch, the noob.
