Default coax short supply

Is there a shortage in the supply of coax ? A ham up the road has been

There was a long discussion here about using compression type F connectors
(and BNC) with RG/6QS coax recently. I suggest that you look it up and refer
your friend to it.

The general consesus was that RG6QS was a pretty good choice for amateur
use. Not the best, but for the usual low power setup, it was ok.

There is RG6QS coax designed for satellite downleads (1-2gHz) so if you
get that it should work for 900 and 1296mHz, possibly 2.4gHz.

It is very important to note that we were talking about COMPRESSION
connectors, which compress from front to back sealing the cable in,


Usually known on the business as 'Snap and Seal' (or 'Snap-N-Seal',
'SNS' etc) connectors. This type is now the only type used in most of
the UK cable TV industry (and, no doubt, in the USA). They are very
difficult to pull off, and are essentially watertight.

For example:

You do, of course, need the appropriate tool.

and NOT crimp on connectors, which are squeezed from side to side and often
fall off.

'Proper' crimp connectors, properly crimped, with the 'proper' tool, are
also hard to pull off - at least, mine are!
