<DIV><FONT size=2 face=Arial>Check the 874 type connector. I don't know about
power rating. These were originally on General Radio Test equipment from the age
of dinosuars. I have a specimen and would not use it for anything much more than
QRP and there it is too much bulk. Check them out anyway.<A

might get excited about these as they are politically correct. They are sexless
or hermaphroditic connectors.</FONT></DIV>

they are threaded <A

<DIV><FONT size=2 face=Arial>Keep in mind what happens in T storms. Before
lightning strikes, stuff happens. An electrical charge develops on your non dc
shunt design antenna. An opposite charge builds up at some other point. This
builds up until a difference of potential builds up which develops an ionized
pathway to your antenna followed picoseconds later by a lightening strike. Maybe
not pico, could be nano. It does not matter but you get the time scale thing. A
number of antennae are dc shunt design. This bleeds off the charge so that the
ionized pathway does not happen. That is why there are not as many lightening
strikes as one would think. Ok, now we have other antennae. For these, the gas
discharge inline dodads are the way to go. There are simpler types (Cushcraft
that are a spark gap) which I would stay away from if you can afford to. If you
look at old lightening protection info, an automotive spark plug was actually
used. Anyway that is our primary protection against lightening as we can't
always unplug when neccesary. </FONT></DIV>

bulkhead</DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>I'd like something easier than
unscrewing the PL259s at my bulkhead for thunderstorms. BNC comes to mind but
doesnt have a native connector for the .400 diameter cable. I've also seen
push-on quick disconnect UHF connectors (<A

I wonder if there is some middle ground?<BR>
