All of which means it is a good idea to have a pulley system to both guy a
long antenna and quickly retract it like you see on mil vehicles. I have
had to go out and remove an 800 spike when entering parking garages, so it
is a good idea to make those mounts easily accessable. I like to put them
where I can reach them from the driver or passenger door. KNOW YOUR
CLEARANCE! I often use an old expendable CB whip for HF reception and go
out and swap antennas when I want to get on the air.
