I purchased the 24' flagpole antenna with 4' extension added later. The materials and construction are very good. Parts fit together very well. Antenna aside, this is a handsome flagpole with flag.
I had no expectations for 160 meters. I purchased the antenna to supplement my EFLW antennas for 40 and 80 meters. Initially all tuned well from 10 - 40 meters using an LDG RT-100 remote tuner, but unable to tune on 80 meters. I upgraded to a Chameleon CHA-URT-1500 1.5 KW remote tuner, but still unable to resonate on 80 meters. I added a Palomar 4:1 balun between the remote tuner and the antenna and now am able to tune antenna well on both 40 and 80 meters.
I have had impressive domestic and DX contacts on 10-40 meters so far. I am hoping that with a little more effort, I can eventually get DXCC on both 40 an 80 meters. Will keep you updated.
