You have to wonder why Heath always used an RCA phono jack for
the feedline connection rather than an SO-239.

(You have to also wonder why we write "jack" instead of "socket"!)

What's the difference between the losses at HF between the RCA phono
jack + plug, and the SO-239 + PL-259?

Someone once told me Heath chose the RCA connectors because they
were easier to solder than the PL-239.
