[CQ-Contest] Antenna slippage on mast

[Bob Naumann]

Guy,

So, is what you're saying that the 20m antenna is slipping on the mast? I
think that you have the 15 on the same mast, but from what you said, it's
not clear.

To stop it moving, you need to either "pin" it as Dick suggests or increase
the friction enough between the antenna and the mast. 

One way to do this is to add more U-Bolts around the mast. If it's got 4,
add 4 more - increase the friction.

73,

Bob W5OV

Guy,

About the only think you can do in that situation is pin the mast-to-boom
plate to the mast. Many commercial boom-to-mast plates have a hole for that
purpose.

BTW, a better place to ask this question is on the Tower Talk reflector.

I have a large 20M monobander with a 60' boom.    It seems that whenever the
winds exceed a certain speed I will subsequently need to climb up to 160' to
repoint the antenna.   My 40M 4 el beam doesn't seem to do this.   It is
definately not rotator slippage because the 15M monobander is lined up just
fine.
 
Any tips/tricks?
 
Thanks in advance,
Guy, N7ZG
