[VHFcontesting] 12 foot rover mast too high?

Hi Pete,

I set my rover antenna mast height to 11.5 feet and it clears everything
except for one viaduct that is only 10.5 feet.  Other than the one viaduct,
I have no issues however it still hits low hanging tree limbs so I try to
avoid them.

Best of luck and 73

To the rovers:

I have a walk-up mast system (Penninger Radio) for my minivan rover beams
that I previously had to construct on-site at each stop. I've been working
toward getting a real ham rotor on the bottom of the mast, and to travel
with the beams up to increase my operating time by not having construct at
each site.

I just put the system together yesterday. The combination of the pivot
device, the rotor, and mast sections I'm using altogether put the top of the
mast slightly over 12 feet from the ground. It looks dangerously tall to me
for driving.

Before I spend more time on getting the mast more stable with some metal
between a ring bearing and the roof rack, do you guys have an opinion about
driving with a mast that high? On interstates and state roads, it shouldn't
be a problem, but I'm wondering if you have a mast that tall with antennas
(I will have 4 ~10' beams) while driving to good sites on heavily-wooded
roads with antenna-snagging low branches.

What would you consider the maximum reasonably-safe height for travel in the
Northeast with it's narrow back roads, tree canopies, and old railroad
bridges (I'm from Pennsylvania)?

Thanks, Pete K0BAK
