Jim - That is my antenna, currently installed as an inverted vee with center at 40 feet. I have about 80 feet of window line. I just tried it with my KX1 using an Elecraft 4:1 balun. [Usually, I use an outboard Z match tuner (NORCAL)]. On 40 meters, I got an SWR reading of 2.3 while 30 and 20 meters were 1.1 and 1.0 respectively. I could probably get the SWR on 40 meters down by changing the feed line length. Of course, this would change the other bands. The balanced antennas are harder to match than the end fed wires recommended in the KX1 ATU manual. I get close to 1.0 on all 3 bands with an end fed 80 foot wire sloping up to 30 feet and a 33 foot wire laid on the ground. I highly recommend the KX1 for portable use. 73 - Rick - K7MW ----- Original Message ----- From: "Jim Miller" <[EMAIL PROTECTED]> To: <Elecraft@mailman.qth.net> Sent: Sunday, February 20, 2005 3:21 PM Subject: [Elecraft] Tuning 88' with KX1 autotuner?
Just wondering if anyone has tried their KX1 with the autotuner on an 88' doublet with a windowline feed? I'm getting ready to erect an 88 footer in my backyard. My height will be around 35ft and I'll have 80 feet or so of ladderline. How did you do the coupling of the ladderline to the kx1, any feedline length issues and how did it load up? tnx jtm (drooling over a kx1) _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
