Clansman Antenna Mount.

Recommended Posts

Posted (edited)

Dear All,

Hoping this isn't a silly question ?

I want to use the Clansman mount, (Photo's A & B) with a 2 metre  amateur radio set in my LR wolf.

In the top part of the mount (Photo  C & E)  there is a transformer / balun.

If I by pass the transformer / balun  (Photo F) and use a quarter or five eighth  wave length of Clansman aerial rod. will that suffice  or am I missing something ?

 

Thanks,

Barrie

It's got to worth a try? vswr meter should tell you the success or not AND it's easily reversible.  PLEASE post your success (or deferred success)!

Thanks for the reply

And that was going to be my next route, however my friend has offered to respray the Wolf so everything on hold at the moment until Wolf prepped, sprayed and ancillaries  bolted back on.

will keep you updated

It isn't a balun as you are going from unbalanced co-ax to an unbalanced whip. I believe from memory that it is an auto transformer designed so that there is a DC path from the whip to ground/vehicle chassis in case of contacting overhead power lines. It may or may not work effectively on 2m. Being designed for the mil band the ferrite may not be suitable. I think I would remove it and just feed the co-ax straight to your quarter wave whip cut for 2m. 

Or you could do some tests with and without it to some distant friend and try and see if the received signal strength changes with and without it.

Gordonb,

Thanks for the info.

Unfortunately it  will have to wait a while as a friend has just offered to re-spray the Wolf in a couple of weeks time, so I’ll be slowly stripping everything off the vehicle.

When It’s all back up and running and radios, antennas etc installed will try an experiment or two and post the results. Won’t be for a while though.

As said, it isn't a balun.  Just remove it from circuit as you've suggested and then use a VSWR meter to cut a whip to a suitable length.  I've done this before and it works.
