Hello:

This will be my first outdoor receiving antenna project.

For running coax between a receive only antenna (30 MHz), and the receiver
in the house,
what are the typical connectors to specify.

Some of these connectors will be outdoors, of course, and this is a
consideration as they will
be essentially inaccessible, and I would like them to remain tight,
functional, etc. for a long time..

I guess for 30 MHz, I don't need the higher freq. fancy N or F, etc., but
should I
go with BNC's, PL-259/259, or...? Why ?

How does one protect outdoor coax connectors ?
Gunk them up with RTV or...?

Are therer "better quality" ones avail. than what one sees in the Universl
cat., such as Silver plated, etc. ?
Worth getting ?

Thanks,
Bob

Are you matching a wire to a cable. You'll need a ''balun''.

I'd get one of the F-Connector types he

as the Cable TV stuff (RG-6, connectors, grounding blocks, etc.) is
ubiquitous and cheap.

Use whichever is more convenient for you to use of the 50 ohm variety
and that would be the BNC or 259. The F type is a cheap connector and
the N is more expensive.

The silver plating maybe overkill but the soldered units are usually
better then crimped.

Outdoor connectors should have a sealant put on them.

Hi,

Thanks for help and suggestions, as well as all the help you've provided in
the past. Really appreciate it.

What sealant would you suggest ?
Just gunk up with RTV, or is there something neater and just as effective ?

Regards,
Bob

Coax-Seal... that along with some good black electrical tape.

On the outside of the putty.

FYI If you buy it as 3M Electrical Putty it costs much less.

The electrical tape? No, underneath. Just leave a bit hanging out and at removal
time everything comes off nice and neat.

Works like a charm.

Gee, that's $10.70 per roll (list)(60" long) vs. the Coax-Seal at $2.99 per roll
(60" long).

How does it cost much less?

Yes that is good stuff to use. Any sealer that can stand up to outdoor
use and keep out moisture will work but they are all kind of messy to
use. Coax-seal is a little easier to cut off and clean up when when you
need to disconnect the coax in the future.

I tape first, then gunk -- it makes ungunking easier if you need/want to
change the connector at a later date.
