[VHFcontesting] Vertical masts running thru horizontal yagis

[Mike Wechsler]

Mark,
Lots of rovers take a non metallic mast and run it horizontal and put three 
or four microwave loop antennas.  I ran my 432 and 222 antennas on a 
separate Horizontal fiberglass
mast.  Look at some photos of Rover configurations to get some ideas. 
Hope this helps with your rover efforts.

Hi.  I'm pondering my likely roving / portable antenna setup for the UHF 
contest and am thinking of mounting a 432 yagi below a 1296 loop yagi.

Does any one have any practical experience they can share re running a 
metallic 1.5" to 2" mast (plus another feed line) thru a 432 MHz horizontal 
yagi.  The antenna in question will be the a M2 21 element 432 antenna which 
would be centre mounted on the mast.  The antenna at the top of the stack 
will be directive systems 55 element 1296 loop yagi.

I'll probably just try this at home before August but thought I would ask 
for comments first.   It seems like a lot of metal to run thru the pattern 
of the 432 yagi.  I'm thinking this is probably not going to work out very 
well but it would simplify the station set up.  In the past I've just run 
one antenna per mast to avoid having to deal with this and I may end up just 
running separate masts for 432 and 1296 and forgoing the other bands.

Any comments are welcome.
