Re: AX1 Loaded Whip Antenna - Elevation and

w7aqk
Dave And All,

 

Hmmm!  I don't quite understand that statement.  Why would you worry about
every dB at your home station but not necessarily be concerned on a portable
setup???  I guess maybe you are saying that, when operating portable, just
get the best antenna possible as opposed to a lesser one.  Well, that's
ideally true, but "you do with what you got"!  Whatever antenna you might
have for portable use, you want to squeeze every dB you can out of it!  I
tend to think it could be even more important when operating portable since
you already apt to be weaker, and that last dB may be the one that gets you
heard!  Home station operators might  actually ignore such issues since they
may already be more than loud enough to be heard.  QRP/portable operators
tend to not have that luxury.

Doesn't much matter.? You're still talking a 3 dB difference at most (50

feet vs 30 feet), and while I will be the first to argue the benefit of

every single dB for normal station operation (see

http://www.ab7e.com/weak_signal/mdd.html), I don't understand the angxt

over that 3 dB for portable operation.? If that's actually a concern,

bring a better antenna.

Re: AX1 Loaded Whip Antenna - Elevation and

David Gilbert
In reply to this post by w7aqk


Well, I actually have three reasons why I think the root of this
discussion has been misguided:

1.  Typical portable operation is for casual fun while camping or just
enjoying the outdoors.  Squeezing out every last dB doesn't quite fit
that scenario.

2.  If you are trying to squeeze out every last dB for whatever reason,
using an AX1 with 50 feet of coax and an extra tuner isn't the way to do
it.  There are better choices for the same size and weight budget.

3.  And if you are using the AX1 with its very high Q, there are lots of
other variables (length of counterpoise, terrain, height above ground,
proximity to other detuning influences, etc) that will have far more
impact on transmitted signal strength than a couple of extra dB loss due
to SWR on the coax.  Wayne made pretty much the same comment in the
context of SWR, but the same holds for signal strength.

Use whatever you want.  It makes no difference to me other than the
misconceptions that come with it.  I've done a LOT of portable operation
over the years, and my first priority has always been to put up the best
antenna I could within whatever constraints I had at the time.  I don't
own an AX1 but it appears to be a fine antenna for its intended purpose,
which was essentially a backpacker antenna usable even for pedestrian
mobile.   However, if I was on a camping trip (tent, cooler, etc) and
wanted to get out better, I can think of better options.  I do own a KX2
and I use it with a homebrew 20m vertical that I can easily carry in one
hand for miles (five 4' sections of lightweight tubing, one of which is
for elevating the radials) and set up in fewer minutes than I have fingers.

It doesn't seem obvious at all to me that it's a knockoff.  There are
only 2 units available and he's asking way too high a price for a knockoff.

Let me add to this post....  Elecraft quality, products and engineering are fabulous.  Yes, I have been drinking the cool-aid for a decade.  Love the entire deal.  Tired of much of the other manufacturers over the years. Have had issues only resolved by selling.  YMMV.  Mine doesn't.

Now for Eric and Wayne to keep providing us new products!

EC2 Enclosure For Sale

Jay Rutherford-3
Anyone need an New Old Stock EC2 Enclosure? I bought it in 2001 and it's never been out of the box, parts still wrapped in paper, assembly hardware included. I'd like $55 shipped USPS in US.

Please contact me OFF LIST if you'd like to buy it.

In reply to this post by w7aqk
I brought along a NanoVNA this trip and used it to array the two counterpoise
attached to my AX1 antenna - adjustments of counterpoise brought SWR down
from 9+ to <2. SNRs in the low ‘teens with a 200mW WSPRlite vs upper 20s -
*inside* a hotel room with sealed windows.

As Wayne said, the AX1 is particular wrt configuration. When it’s good, it’s
very, very good, but when it’s bad, it’s terrible. The NanoVNA is pretty
cheap/light kit to add if you’re not bringing an ATU-enabled rig.

Re: AX1 Loaded Whip Antenna - Elevation and

David Gilbert

I think users of the AX1 would be better off thinking of IT as the
counterpoise, and making the most out of what they normally consider to
be the counterpoise wire.

Look at it this way.  Unless you have a lot of current on the shield of
the coax (in which case IT is doing a lot of radiating), roughly equal
currents are going to try to go both ways from the feedpoint ... into
the AX1 and into the "counterpoise" wire.  The AX1 is typically
physically shorter and it certainly has more loss, and since the
radiated field is a function of net current and length, in most cases
the counterpoise wire is at least trying to do the most radiating.  I
say "in most cases" because the typical position of the counterpoise
wire puts it along the ground or near some other RF-sucking structure.

In my opinion, probably the best way to use the AX1 is to put the
counterpoise wire as straight, high, and in the clear as possible and
let the AX1 act like the shortened other half of the circuit (i.e., the
counterpoise).  If that isn't possible, make the counterpoise wire as
straight and vertical as possible ... climb a tree and let the wire hang
down.  ;)

If I had a good EZNEC model of the AX1 I'm pretty sure I could prove
that assertion, but for those who have an AX1 I'd bet some field
strength experiments would bear me out.

I'm not saying that the AX1 isn't a worthwhile investment, and I'm not
saying it doesn't radiate.  I just think there are some misconceptions
on what it's actually doing and how to best make use of it.

It’s designed for /PM and stealth ops. In many other situations, of course, a longer/higher antenna will be more efficient.

Re: AX1 Loaded Whip Antenna - Elevation and

David Gilbert

Certainly true, and it's great for that, but a lot of the posts here
have been about people using it for more than that ... like camping and
restrictive locations.  I'm just saying those folks could get more out
of it by treating it differently, and it would serve a very useful
purpose in that function if they did.

Re: AX1 Loaded Whip Antenna - Elevation and

Brian Hunt
In reply to this post by David Gilbert
I think you'll find that for a short vertical radiator and a single counterpoise wire the maximum radiation is in the direction of the wire. EZNEC confirms this and I've tested it with a friend the length of California on 40 m where with the counterpoise pointed away from him I could barely copy him, flipping the wire 180° brought his signal up significantly. He saw the same thing on his end.

Re: AX1 Loaded Whip Antenna - Elevation and

Grant Youngman-2
Not trying to start a disagreement here, but I don’t see the point.

If you want to run a wire antenna, then, good gracious, run a wire antenna.  They work pretty well portable.  I carry two in my bag.  But I fail to see the rationale of using the AX1 as a “counterpoise”.
For quick low profile portable, the AX1 works as well as you can expect a very short loaded radiator to work.  For that purpose it’s easy, quick on the air, and does fine.
