My Quantar repeater will be located at a fairly RF congested site. Is there any real advantage to the Tripple Circulator option that adds two more circulators to the standard single circulator?

Larry,
It sounds like those little "RF's" might get confused travelling around in all those circles!
OTOH, as long as it happened to the onces coming down the antenna and not the ones going to the antenna, that would be a good thing!

Hi,
If the site requires more isolation than a single isolator provides (not unusual on many crowded sites), then Motorola's internal option might be what you need - but if you are feeding a combiner system that already has a single or dual isolator in it, you probably don't need the optional extra ones.
Additional isolators also provide slightly more protection to the transmitter in the event of antenna or duplexer failure (and the radio is still keyed up for long periods, like in a pager system)... even if the first one fails, you still have some protection! Not a real likely scenario, but possible..
