I have a 43-foot high x 130-foot long inverted-L that I use on 500-KHz with a HB base coil to ground. I tap 2-1/2 turns from the bottom to feed with coax using ferrite chokes for common-mode currents. Works very reliably. On 500-KHz I have winter and summer taps as the frozen ground changes

Just curious if anyone else is using the K3 internal tuner with a 43' vertical. Will handle all the bands 10 - 160? Or do I need to purchase an external tuner. I'm about to put one up to get me on the air. This will be a temporary antenna while I build the antenna farm here at the new qth.

I hope you have a 4:1 Unun at the antenna. I am going to play with one of these antennas at 31ft and 43ft for an antenna down at J6 as they are light and easy to take and seem to work on all bands. It would make an ok backup/secondary antenna. On 9/18/2011 10:49 AM, Phil Debbie Salas wrote:

I ran my K3 with internal autotuner on the DX Engineering 43' fast-taper vertical with their 4:1 UNUN with excellent results on 40 meters and up. I tried a couple of local qso's on 75 and it worked ok, but I was only running 100watts on a KW band. I tried loading on 160 meters and think it did
