Re: [Elecraft] AX1 Loaded Whip Antenna - Elevation and Counterpoise?

[David Gilbert]

Then you'd be using the T1 to partially drop the SWR on the coax, but it 
still wouldn't be anything close to 1:1 unless the T1 has a much broader 
range than the tuner in the KX2.  You'd still have some additional coax 
loss due to SWR (but less loss, of course) and you'd still need the 
tuner in the KX2 to get a match that wasn't a problem for the KX2.


I have to wonder how much loss there is in two tuners each trying to 
match a really bad load, and it still seems to me that the better 
approach if you're worried about every dB is to use a better antenna.  
Using a really short whip like the AX1 with 50 feet of coax and two 
tuners seems like a poor choice of tradeoffs.

Let's look at this realistically:

1.  The antenna tuner in the KX2 is rated to be good up to 10:1 SWR.  Let's 
assume it's good to 15:1.

2.  Let's assume you're using a decent cable for portable operation like RG-8X.

3.  Let's assume that the length of your coax when operating portable is not 
much more than 30 feet long.

4.  Let's assume under the current solar flux conditions you're spending most 
of your time on 20m or lower in frequency.

30 feet of RG-8X has a loss of 0.4 db or less for that length at those 
frequencies, and per the charts in the link below the additional loss due to a 
15:1 SWR is no more than 2 dB.

Maybe it's just me, but I don't think that justifies dragging along a remote 
tuner.  You could recover a heck of a lot more dB by simply bringing a somewhat 
larger portable antenna.

Re: [Elecraft] AX1 Loaded Whip Antenna - Elevation and Counterpoise?

[David Gilbert]

Scroll down to the original post.  We were talking about a KX2 with an 
internal antenna tuner.  Presumably the tuner works as it should to 
present the proper load to the finals.

Re: [Elecraft] AX1 Loaded Whip Antenna - Elevation and Counterpoise?

[Phil Hystad via Elecraft]

Some points…

“…dragging along a remote tuner”

Surely you are kidding or you get the award for hyperbole of the day.  The T1 
fits in my shirt pocket!  It is zero effort to bring — no “dragging” required.

And, I operate with 50 feet of coax because carrying multiple different lengths 
of coax on various trips where I operate portable does get into dragging.  
There have been some situations where 50 feet has not been enough such as in 
one national park where the convenient picnic table was quite a distance from 
the nearest convenient tree.

Re: [Elecraft] AX1 Loaded Whip Antenna - Elevation and Counterpoise?

[David Gilbert]

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.

Yeah, i didn't catch that he was going to use the internal tuner and just
forgo the external one at the other end of the coax.

Re: [Elecraft] AX1 Loaded Whip Antenna - Elevation and Counterpoise?

[Wes]

I haven't been following this thread closely but I think Dave makes good 
points.  As to the final fold-back, if I waded through this correctly, I 
understand that the OP has the built-in tuner in his KX2.  That solves that issue.


BTW, SWR = 15:1 is a return loss of about 1.1 dB, not 3 dB.

Let's assume it's good to 15:1.

2.  Let's assume you're using a decent cable for portable operation like
RG-8X.

3.  Let's assume that the length of your coax when operating portable is
not much more than 30 feet long.

Re: [Elecraft] AX1 Loaded Whip Antenna - Elevation and Counterpoise?

[David Gilbert]

Rather little of this discussion makes sense to me.

Let's look at this realistically:

1.  The antenna tuner in the KX2 is rated to be good up to 10:1 SWR.  
Let's assume it's good to 15:1.


2.  Let's assume you're using a decent cable for portable operation like 
RG-8X.


3.  Let's assume that the length of your coax when operating portable is 
not much more than 30 feet long.


4.  Let's assume under the current solar flux conditions you're spending 
most of your time on 20m or lower in frequency.


30 feet of RG-8X has a loss of 0.4 db or less for that length at those 
frequencies, and per the charts in the link below the additional loss 
due to a 15:1 SWR is no more than 2 dB.

Maybe it's just me, but I don't think that justifies dragging along a

bringing a somewhat larger portable antenna.

I think a T1 at the base would make a noticeable difference if the coax were 
more than a few feet long and the whip's resonance well removed from the target 
operating frequency. Short whips can be extremely narrow-banded.

Re: [Elecraft] AX1 Loaded Whip Antenna - Elevation and Counterpoise?

[J Chester]

Bret,

I’ve just submitted a review of the AX1 to Practical Wireless magazine, which 
should appear be in the October issue, published end of September.

I found it worked well on the tripod. The key to getting the most out of it is 
to let the counterpoise wire fall to the ground about 3 ft or so from the 
radiator. As a very short base loaded antenna, I don’t think an extra foot or 
so of height will make a lot of difference. Your extra counterpoise wires is 
probably the best thing to do. More details in the article

[Elecraft] AX1 Loaded Whip Antenna - Elevation and Counterpoise?

[MaverickNH]

I've got my little 20m AX1 and 3 tuned counterpoise wires on a 4ft tripod
with wires extending to plastic chairs 3ft off the ground too. If I got that
whip up to 2m above ground with sloping wires, would I gain much?
