Sam,
Passive repeaters can work in some instances. The key factor is gain
and electrical separation. I have done it in the Denver area on a
microwave video link to get around the Downtown area with a pair of 4'
solid dishes. It works, but not always.
Here is something to TRY. No guarantees that it will work for you, but
it is worth a try. If you were to ask me what the probability was I
would say it was a very firm and definite maybe.
Use 2 24 dbi grid dishes (19 dbi panels might actually be better due to
the signal rejection they offer to the rear.) and separate them
vertically by at least 5' on the mast. Connect them with as short a
piece of cable as you can. Use good practice. As in: drip loops, etc,
but keep the cable as short as you can and make it LMR400 or an
equivalent or better. Hard-line would be best. Get things aimed up
using a laptop hooked to each antenna individually via whatever radios
you need to connect to each end.
Like I said, this works sometimes. Electrical separation so the
antennas do not cancel each other out and antenna gain are key.

Subject: [smartBridges] Passive Repeaters
Has anyone used a passive repeater before? (I may be calling that the
wrong thing....it's where you wire two antennas together with just a
piece
of LMR-400 to relay or "bounce" signal around a corner, over a hill,
etc.)
I have a customer that has a hill in between him and my AP.
/\
/ \
AP / \ Customer
The distance from the AP to the top of the hill is about one mile, clear
line of site. From the top of the hill to my customer is about .5 miles,
clear line of site. There is no electricity out there, no other
customers
to be gained by putting up another AP( or APPO to bridge the signal) so
this is really the only cost-effective way to do it that I can think of.
IO was thinking about two yagis on top ot the hill, one pointing at the
AP
and the other at the customer, and then giving the customer a yagi too.
Will this work?
Thanks
Sam
