I tried that in my shop (metal lined) with the pickup inside and antenna
on the roof. Never could get it to work. An HT behind the shop worked
better (shop was between the HT and the repeater 6 miles away.

## passive repeater system ! Now that sounds like the ideal ticket.
2 ants, and one short coax between em.
I assume kellys remote cottage is for 2-4 months in the summer time,
like
June to Sept. Folks go to summer cottages to....get away from it all,
but still, phone service of some type, for emergencies is a must.

Back in the olden days I tried that a few times and didn't have much
luck. We'd be installing a new cell site where ground level signals
from other sites were pitifully weak. Which is why we were installing
a new tower there I guess. Needing comms, we carried an 700 MHZ yagi
with us, and as soon as the tower went up, we'd slap that yagi up
there at 100' or so and search for the best Nextel signal, using a
direct connection to the phone (we had a modified phone with an
antenna jack).
At 100' it was usually easy to get a reasonable signal. But there
never seemed to be enough radiated signal out of the ground omni to be
of much use as a repeater. If you connected the feedline directly to
our special phone, it was fine. But you could hold a regular Nextel
phone one inch from the omni repeater antenna, and it was of very
dubious value.
It was disappointing.
Nowadays, it's rare that I'm in a spot without usable signal level. I
carry both AT&T and Verizon phones. Usually I'm good on either
network, but in Michigan's U.P. for example, both carriers are needed
depending on location.
