Hi Bill, A quick fit solution that I have used on many demos is to use a plastic clip,the type used for fixing central heating copper pipe to a surface. The older type seems better (and stronger) - It is ready drilled with a central hole which in my case also simply self tapped onto the thread of the camera fixing bolt. The other option is to remove the camera fixing bolt and replace it of course with a nut and bolt long enough to fit the plastic clip. I used it with an Arrow antenna which is of course "square" tubing, it was not a secure fit. --- MY SOLUTION - was to fit a short piece of central heating copper pipe to the Arrow antenna "At the correct point of balance" . If you want to make it more secure a cable tie will help with this problem. Regards Ken Eaton GW1FKY Amsat- UK Amsat NA
