I have been using one of these for more years than I care to remember. I use an auto atu but find the antenna excellent, surprisingly It also tunes flat on 10 mhz.
Suprizingly good antenna
I have tried a few wired antennas over the years. But this antenna in a inverted V formation is quite something. I have the centre 40 feet up with the ends about 8-10 feet up from the ground. Great care was given to spread the different bands. I get 1:1.5 VSWR best case and 1:2.0 VSWR worse case.
The performance is very good with at least 2 S-points above a Dipole. It is also quiter. Overall it is a great aerial and I am pleased with it.
One of the best HF antennas I have used
Not having the luxury of space to house mononband beams and suchlike, this antenna is a true performer. Nothing I have put up since - verticals and loops matches the performance of my DX-CC
I could only just squeeze it into my garden and I am glad I took the risk. In my next house I would certainly be striving to have a DX-LB Plus in place - that would just be amazing.
See my QRZ page for images of this antenna installed. I made a centre support for it from non-conductive materials so it is away from the building/ground electronically as much as possible. See M0SAZ
5 Star antenna!
