[VHFcontesting] [FFMA] MAST FOR ROVERS

[Terry Price]

I am very lucky to have a 40' and a 55' pneumatic mast on my 1994 Dodge van
for roving. Using compressed air or a nitrogen tank to raise the antenna
stack is VERY nice, fast and effort less! However, if I didn't have these, I
would build a telescopic mast using this stuff.

I can't remember where I saw it or who had it but a rover in the Midwest I
believe had a mast made of this stuff and it was one of the best I've ever
seen. He had a crank system to raise and lower it. It's not cheap but it was
robust and it worked very well.

I
don't think the following would represent the best solution, but I too have
been thinking about this and thought that I would try to use some of the 1m
fiberglass military poles.  My thought was to used adjustable clamps above
and below each joint., with a total of 5 pieces that you be a length of 16'-
9".  Which would perhaps give enough height to clear vicinity obstacles,
like vehicles, RV, tents, etc

Been working on a 3L 6m antenna and probably just the one antenna to start
with.  I believe that this mast would support a HO Loop for 2m and/or 70cm
as well.  Perhaps a small rotor could be installed at the 2nd joint.   I
think the "Armstrong" rotor with be my initial method.

My biggest concern is managing a scope out pole, as I am now 73 I don't
think that I will be getting any stronger in the coming years.  hi hi.  

I definitely would be interested in what others have to suggest.

Recently purchased a mast support for Truck receiver hitch.   "Portable"
five element beam is in possession.   What type of portable masts are being
used that can be easily carried inside pickup bed or short SUV?????

The mast support:  https://smile.amazon.com/gp/product/B07ZGBRT61    I'm not
recommending it or otherwise, hopefully it works for Rover use - parked.
