I have an older RV in which we had the roof done in Rhino Coat. I did not want to compromise the expensive roof so decided on a ladder mount. Making sure that one can step over the lift assy, I wanted it low as possible. It is a used unit and it didn't come will all the stainless 1-1/2 saddle clamps so I had to make do with what I had. I did create two middle brackets out of stainless pipe. This is where I wished that I had a hydraulic press and a drill press. No luck there so everything was done by hand. All the hardware is non-magnetic. So far, I have had good reports. The RV metal frame works well but I did add 1 40m elevated radial. I can add more elevated radials as needed. It goes up and it goes down. I still need to make a nesting receiver for the antenna whip. That tall black pipe next to the ladder is a home brew 2in EMT pipe for a generator exhaust venturi. All the cables do come apart at the antenna base for transport. I am curious what folks do with the maintenance of the actuator and pivot joints? Those actuators are not cheap. Antenna: TH 100A-HP Antenna Controller: TurboTunerII IC-7200/SCS P4 Dragon in P3 mode.
