Re: Portable VHF antennas and rotator
toggle quoted messageShow quoted text
Hi John. Well currently my set up is slightly unorthodox. I used to have a trailer with a pump up SCAM on it. For that the rotator did go on top in the “normal” fashion.
However since the SCAM pump up became defunct and I acquired a new Yaesu rotator I have a set up where the rotator sits on a plank on the ground (which was meant to be partially under the wheel but isn’t). I then have a bar strapped to the roof rack and the poles go up through a tube fixed to this with the antenna on top.
The rotator is a “standard” Yaesu and operated from 240v – but I run a generator which also runs a 240/12v psu to drive the rig.
However I should say that my main target is the ACs (SSB/CW) rather than the FM section but I enter the FM as well as I am usually set up. Hence I use horizontal beam antennas – which sort of defeats the original intention of the FM bit but I’m not the only one that does it.
No reason why you shouldn’t use a vertical antenna and get it as high and in the clear as possible. Good co-ax is a must if you don’t want to lose to much Rx signal and you might even think about a masthead preamp although they are of more benefit if you are using beams as then you can null out some of the signals which can be a problem with an omnidirectional antenna!
Have a chat further sometime at Club.
