Hi everyone,
I just finished building my 3-band KX1 with the internal ATU. It sure is a
great little rig! Today I did my first experiment with a quick-deploy field
antenna. I had a 40-ft radiator thrown up into a tree, with 3 radials as a
counterpoise. Most of the radiator was at about a 45-degree angle. The radials
were cut at 1/4 wavelength - one for each band. The antenna system was
connected to the rig through a BNC/binding posts connector. The internal ATU
gave me an SWR on 30 and 40 meters of 1.7:1 and on 20 meters it was 1.1:1. I
guess this is OK but the 1.7:1 matches showed a reduced output power and I would
like to do better. I generally like the idea of this kind of antenna, but any
and all suggestions that you might have would be very welcomed.
Thanks and 73,
Paul – N8XMS
