[Elecraft] K3 Ant 1 and Ant 2 Isolation?

Wed Jul 9 22:10:07 EDT 2014

Hi to Rich and the group

During field day I ran my KX3 with the tuner from the KXPA100 at 5 watts. I had my 44 ft doublet fed with 22 ft of window line on my 24 ft painters pole in the center with a 10 ft PVC support on each end of the doublet. I had a 33 ft MFJ fiberglass mast with 29 ft of wire fastened to it as a vertical about 2 ft away from the support for the doublet. The doublet through a W2DU balun was on antenna 1 and the vertical fed against the frame of my fiberglass camper was on antenna 2. Both antennas were pre tuned by the tuner on each band before field day started. I could chose either antenna instantly. Most of the field day the doublet was about the same as the vertical and I used it. I found the vertical to be the better antenna in the late evening and night on 40 meters so I used that. There was one weak point to my station and that was me as an operator but the KX3 and the 2 antennas worked great. I made 118 CW 5 watt battery search and pounce contacts and could have made many more if I was just a better operator. I hope my experience can be of some help. I have pictures on qrz.com not of field day but of the different parts of my station I put together for field day.

A 31' piece on wire running vertically down the pole and also a G5RV supported by that same pole.  Then just connect them to the K3 Ant 1 and 2 jacks and away we go, however should we expect to flood the Ant jack which is not in use with RF due to the antennas being so close?
