Re: [Elecraft] Antennas for KX-1
(1) Wire up in a tree, (2) Pac-12. Between those two, you're taken care of with the KX1. 73 de Alex NS6Y. On Jun 29, 2006, at 6:20 PM, J.

Re: [Elecraft] Antennas for KX-1
I was out of town on a business trip this week, which gave me a good opportunity to try the antenna suggested by Bruce. I used his 68' with the 33' counterpoise. The kx1 obtained a flat match on 20, 30 and 80, but 40 was 1.9. I then tried Ron's suggestion. I had a 13' piece of wire so I wrapped it around my glasses case, which was approx 1.5" x 2.5", and this gave me a flat match on 40, but drove the swr up on the other 3 bands. It's not much trouble to clip/unclip the glassed case coil, so I was quite pleased. I will now make a small coil and keep it with the antenna. This set up worked very well for me. Thanks Bruce and Ron. Paul On 6/29/06, J. Coote <[EMAIL PROTECTED]> wrote: I've been following the 4-band antennas for KX-1 thread. Interesting and a real challenge for field operations.

RE: [Elecraft] Antennas for KX-1
In an earlier post, I mentioned using a small inductor - such as some enameled wire wound on a plastic 35-mm film can - with a number of tap points to add inductance to the antenna. It goes in series with the "hot" side of the KX1 output. That will usually let you adjust the electrical length of the antenna to bring it within range of the ATU without having to go out and fiddle with the length of the radiator itself. The KX1 ATU is more limited than the other Elecraft ATUs but it still has a very useful range. It's not necessary to be close to 50 ohms non-reactive for the KXAT1 to provide a good match.
