Default Cut GPS Antenna Wire??

However, if you intend to cut the cable into two pieces and then splice
these
two pieces together, you'll have big problems. At these frequencies

losses
will
be huge and the impedance change large enough to (possibly) damage your
unit.

I too, am a long time amateur radio operator, and know quite a bit about
electronics/radio.

What I don't see, is how signal loss, and/or impedance changes, will
"damage" the unit.

GPSRs are receivers, and receivers only (outside the non-incidental spurious
emissions from normal operation), the worst that could happen, would be a
loss in RX signal strength. I cant see causing any damage to a GPSR by
changing the antennas impendence, other that poor(er) performance.

Sorry, i was stuck in TX mode lol. You are right. For a receive only
unit a paper clip stuck in the back won't hurt it. Heck, a paperclip would
just about be a 1/4 wave dipole at those frequencies!
