If your intent is to experiment with the cheap duplexer, what I have to
offer is irrelevant. However, if you aim to build a repeater, consider
getting your isolation over distance (much greater than 10m). Put the
transmitter and receiver a few km apart and link them using another band
authorized in your area (440?).

I encountered this in Key West Florida some years ago. Worked fine there.

How fine is fine?

Good question. Coverage was entirely satisfactory over the entire island
and several miles up the Overseas Highway. I never used anything more
exotic than a rubber duck. However, Key West is small and all the keys are
very flat.

That's our problem. Jerusalem is high (3,000 feet ASL) and loaded with hills.
There are spots in the city where there is no cell phone coverage. The cell
phone companies go nuts trying to fill the holes, but there is a lot of NIMBY
here.
