"---RCA connectors, will there be a material difference in insertion
loss?"

The RCA pin size is large enough for low resistance contact, and
insulation quality can be good enough for low leakage. RCA connectors
were routinely used in Motorola 2-way radios to make connection to its
internal receiver 455 KHz intermediate frequency filter. This says
nothing about possible loss but does indicate suitabikity for some RF
applications.

Outside world RF connection to Mottorola 2-way radios was usually via
the familiar "UHF" (SO-239). These stay connected when yanked and are
simple and easy to connect to the coax. A bonus is that the
center-conductor pin socked is designed to accept a banana plug.

All common coax connectors are usually too short to represent much of an
impedance bunp.

The RCA connector has been demonstrated to show a flat response from DC
to Light. The only problem with this connector is that it is hard solder
coax to the blasted thing.

Can you direct me to the data that verifies this?

Take a look at http://www.nwham.net/w7zoi/rca_plugs.html for an example of
using RCA connectors at VHF.

i just tried to shine a laser through one and the wire got in the way...
100% loss i would say.
