[UK-CONTEST] Spiderbeam fibreglass 12m pole

[Callum M0MCX]

Half a meter is ample Clive, I've been running one of these 12m poles for a
couple of months on test at this QTH and on-and-off at the scout hut for
various experiments (also through a couple of heavy stormy nights which saw
it bending over dramatically). 

I put a jubilee clip around the very bottom to stop any tendency for it to
split and we sleeve it less than 50 cms, possibly only 35 onto an aluminium
pole. Works fine and not broken yet!

I blog about it here: http://www.m0mcx.co.uk/?p=100 

Make your own mind up but seriously, I've never sleeved it more than about
40cms (waste of pole!).

Cheers,

While others were busy thinking outside the box, I cut it up because I
needed some cardboard for a project I was making.

Hi list

Somewhat off topic, I beg your indulgence.

Some while ago I bought three of these to replace my ageing Butternuts 
in a W1CF array. However, owing to the overgrown state of that part of 
my garden ( I use that word in its loosest sense!) I have been unable to 
carry out the necessary work. Recently I bit the bullet, and employed a 
couple of lumberjacks to clear the necessary scrub. Despite sleeping all 
night, working all day, and having buttered scones for tea, they 
actually did a tidy job, and I now have quite a clean canvas on which to 
proceed.

I had also procured some tanellised cylindrical section fence posts and  
reduced the diameter to fit the base section. So far so good. I note 
however that the supplier specifies that only 0.5m is necessary to be 
inserted into the pole from ground level to be self supporting to the 
full 12m height. I must say that this seems rather small, and I 
personally would have thought that 1m would be required. The latter 
would clearly make it more difficult to lift the pole onto the post 
single handed, especially in a breeze! So I wonder if anyone has 
practical experience and can comment on the required height of the 
ground post?
