When adding a PL-259 connector to a radio that doesn't have one (a radio
that is set up for longwire only), is it OK to just wire it straight in, or
is it best to add some sort of impedance-matching circuit? Obviously the
long-wire connector is going to be high-impedance, while the coax coming in
will be 50ohm.

I often see radios that someone has added the connector. I'd like to add
one to an old DX-150A, just for convenience since my longwire comes into the
house via coax. A already use a MLB between the longwire outside and the
coax; the antenna works great on radios with a 50ohm input.

Any advice? Thanks.

The following free advice is worth every penny... :-)

When you say you want to put a connector on the radio, do you mean the
male (PL-259) or the female (SO-239)?

Don't worry about matching the impedance. It is relatively non-critical
for short wave listening. However, you may want to devote a little
attention and thought to some kind of lightning protection.

Finally, if you mean an SO-239 to be mounted on the radio, I vote "no",
only because IMHO, it buggers up the radio and reduces what ever resale
value it may have; however, this is just my personal pet peeve.
