[UK-CONTEST] GM1J EU92 IOTA Report

[Ian Pritchard]

Hi Chris ..

If you're going to use a spiderbeam you may be intersted in this ...

Some of the pictures in this link show the arrangement I used with my spiderbeam

They are quite easy to erect single handed ...providing the ground is horizontal!  I made sure the geometry was correct for four way guying and then simply walked the mast vertical.
The key to sucess is to allow the base to pivot 90 degrees without it  twisting. I made a simple short wooden "cage" to fit over the bottom of the spiderbeanm pole, this then swivels on a steel rod which passes through the top of a short piece of scaffold pole sriven into the ground.
