I followed the URL after "See our galleries..."
I looked for SSI refit, and didn't find it.
I looked for upgrades/electronics and failed.

So I admired the generally nice quality of the pix, and gave up.

I can only suppose you were extending the center coax conductor at some
connector with a wire, in order to stretch through a bulkhead.
This is not good practice.

Solid dielectric, double shield, preferably not pvc sheath which gives off
acid decay products. Choose the correct characteristic impedance. Coax is
offered in 50 to 70 ohm impedance. Above all: minimize I said MINIMIZE the
number of BNC coax connections. They are lossy. You could consider low
loss type connectors but it adds to the general confusion and cost I know.
I hope you don't mean what I THINK you mean when you talk about jumpers.
NO WIRE JUMPERS!

Hi, Brian,

Yes, when I said jumper I was referring to a short length to extend, or, in
the particular post, just use as a very short feed line, to test the antenna
(having previously proven the radio good).

I have (in the end result) either 3 or 4 connectors, depending on how you
look at it. First is at the radio. Second is at the connector which had to
be bolted, so to speak, to the bracket, as the metz antenna threads don't go
all the way through it. However, having said that, in my test which proved
the antenna and the radio, I note that the metz has a very long male inside
of it, a nylon bushing keeping the antenna feed short enough, against it,
and then the connector piece which doesn't have threads all the way through
it.

If you look at my gallery, under SSI refit, then upgrades/electronics,
you'll see the bulkhead connector I had to use to get the Metz stem long
enough to connect, and the end result on the bracket at the top of the mast.

Numbers 3 and/or 4 would be the double male adapter I had to mount to the
top of that bulkhead connector to make the metz mount on it.

HOWEVER, you've stimulated a thought which I presume would work: If I take
that nylon bushing, stick it back in the Metz, and screw the body of the
coil onto my bulkhead connector, that connector should replace the Metz stem
reducing the connectors by either one or two.

Thanks for stimulation; let me know, any of you, who find fault with that
conclusion (replace the Metz stem with the bulkhead connector).

So, if you conclude that the antenna itself should not be counted in
connectors, I'd have two - one at the radio, and the other at the antenna.

Am I correct?
