[Elecraft] Portable Antenna
Well, this works the best for me for portable. From the ground up- a speaker stand, a 15' painter pole, a right angle pole to antenna mount, a "gum drop" antenna mount, a ham stick and two 20m radials. This works for 14MHz and up as the ham sticks are a good portion of a quarter wave. When out in the clear it is an excellent antenna. My second antenna is a Buddi stick and two radials. It is smaller and easier to transport. Used the last time on a 9th story balcony. Your results may vary.

Re: [Elecraft] Portable antenna for KX3
After buying numerous antennas and spending way too much money on them, I finally came up with a good performer. The best part its cheap easy to build and erect in a short time. It's only a 33' piece of copper wire with a 33' radial when used as a vertical. It can also be used as a sloper, or a dipole just as easy with just a few extra's. 73, Fred/N0AZZ K3 Ser # 6730--KX3 # 5210--K2/100 # 6470-KAT100 P3/SVGA--KAT500--W2 Amps Elecraft KPA500 HF/6m--Alpha's 9500 HF--87A HF--Mirage B-5030-G 300+w--(2) B-5016-G's 165w 2m -Original Message- From: Elecraft [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Michael Marx Sent: Monday, March 09, 2015 8:05 PM To: aar...@gmail.com; elecraft@mailman.qth.net Subject: [Elecraft] Portable antenna for KX3 I have a Transworld antenna. www.twantennas.com http://www.twantennas.com/ They are expensive.

Re: [Elecraft] Portable antenna for KX3
Maybe it's just me, but the KX3 has a nice automatic tuner, and wire is comparatively cheap and one can do an infinite number of different antennas. I bought 250' of #26 stranded copper-over-steel antenna wire, and the biggest problem I'm having is choosing among the possibilities. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
Re: [Elecraft] Portable antenna for KX3
Gotta agree with Frank on the AlexLoop... When it is adjusted and you stay put on a frequency for a while. I disable the internal tuner when I use the loop. I find that the tuner is useful with my other portable field antennas, the SuperAntennas MP-1 and a random hank of wire. I find the MP-1 to be best when I have a good ground plane (car roof, porch railing, etc) and I am just tuning around. The random wire is great when I have the space and a tree. Each has it merits and its issues, but when I have the loop set up and properly tuned, it is the best compromise in a portable unit.

[Elecraft] Portable Antenna
Some experience here with the PAR EndFedZ EF-10/20/40 may be of interest to the group. As you all may know it is a self-resonant half-wave QRP antenna - 25watts continuous - for 40, 20 and 10 meters. It requires no counterpoise and has a sealed matching network at the feed point end. I'm using it in a second floor bedroom with the matchbox at the top of a window, 25' from ground. The other end is tied to a tree, 20' from the ground. The matchbox is connected to the transceiver with a 4' run of coax. Now the interesting part. I've connected a 39' counterpoise to the transceiver. It snakes around the baseboard and into a closet. I can now operate on all bands, 80 through 10. Except for 80 and 30, the SWR is under 4.0. On 30 I bypass the matchbox and connect the transceiver antenna center conductor directly to the output of the matchbox with a 4' wire, and the SWR is less than 3.0. On 80 I short the input to the matchbox with the same direct wire, and the SWR is in the range of 4 to 6. My Icom IC-703 (10 watts max.) internal tuner matches all of the above easily, as does my KX-1 on 40, 30 and 20. (I haven't built the 80-30 board yet.) At some point I may get a second EndFedZ for portable use. At present I use an MP-1, Buddistick tuned (length adjusted to a quarter wave) counterpoise, and the KX-1 for casual operation on vacation. For serious portable work I use a Buddipole or Buddistick with a Yaesu FT-857. All great antennas.
