There are two types of "Denso" tape, though. One is the greeny-brown 
stuff that used to be called Sylglas - completely waterproof but 
horrible to use.

The other is dead black, looks like a very thick PVC tape with a 
non-stick interleaving sheet, but is actually mouldable like putty. This 
is the best I've ever used - totally waterproof, sticks instantly to 
itself and to PVC, bare metal and many other surfaces, but does not 
stick to your hands. This too is made by Denso, but it only seems to be 
commercially available as an aluminium backed flashing tape.

The same material is also available as an accessory for Andrew cables, 
eg as part of a ground clamp mounting kit where it is used to seal over 
where the jacket has been cut away.

This mouldable black tape is absolutely not to be confused with 
Coax-Seal, which is a different and very inferior product (and also very 
messy).

The type N coaxial fuse. If everything is perfect, they will handle as 
much as 1.5kW at 70cm... but that is a very big "if".


GL with the snow. Over here on the Wet Coast it's just normal heavy 
rain.
