I am just getting back into cb after a few years (25) away and have been using a TTI 880 rig into a Wilson 1000 in the car but thought I'd bring the rig indoors and bought a Thunderpole 1/2 wave only to discover no destructions or co-ax.

I am assuming that twig is assembled by clamping the telescopic sections and capped with the bung supplied.
Query 1
Is it OK to assume that just blocking the slots with next section before clamping will give the correct length.( I assume it would be a good idea to seal the joints so no water can get in - is silicon OK.)

Query 2
What is it best to mount the twig on - I am assuming it uses the mounting as a groundplane so any recomendations on sizes of pole etc or is it a case of suck and see.

there should be marks on the sections to show the depth wich they interl;ock the exception is the bottom joint which should go in about 6 and 1/2 inch to 7"
whioch sets the swr mount on a pole and the higher the better on a chimney useing 2 mounts with a 6ft pole should do the trick and seal the joints with electrical tape or silicon to stop water gettingin

Thanks for that - I found the marks.
Unfortunately mounting on a chimney is a bit problematical - I live in a static caravan :roll:
I'll try fitting it on top of the pole holding my satellite dish and tv aerial (3x1.5mtr interlocking poles from Thunderpole that is attached to a handrail post on the decking).
I nipped round to Thunderpole earlier and picked up co-ax and plugs I forgot yesterday so will get it erected sometime soon =D>
