there any sealing techniques that I should observe??
They're recommending that?!? Good grief. I suppose if you've got a
couple layers of tape over the joint first, you'll be okay.
I don't recommend it. Regular RTV (room temperature vulcanizing)
outgasses ascetic acid which is not recommended around electrical-type
You don't see any professional tower/antenna installers using the stuff. What
they do use is a good tape (e.g. 3M 33 or 88) and then a layer of butyl
rubber vapor wrap. I hate CoaxSeal but that's the kind of stuff. Professional
vapor wrap versions do not stick to the connectors (unlike CoaxSeal) and are
available from _www.championradio.com_ (http://www.championradio.com) .
If you've got your heart set on using RTV, use the kind for aquariums
which does not outgas the ascetic acid.
