Hi Dave, I have a similar situation (MA-550 bolted to the house) and here's what has worked well for climbing it. Make bolt-on steps of angle aluminum and all-thread rod. The angle aluminum should be
In my experience, most multi-band verticals that work on more than three bands start to become seriously compromised on the lowest band. Sometimes they are compromised on the highest band, as well. T

Yeah, but actual performance would depend so greatly on local ground screen characteristics, terrain, and quality of installation and connections that any one-time tests would have little merit on a
