Thanks for the input here. I thought something was a bit strange for the
distance. I'm thinking in the duplexer, but am going to have to hook the
transmitter up and have someone a distance from the repeater hear the
signal, almost bet it is there. As far as I can tell, the recieve side of

A simplied formula for use when both antennas (I know, antennae) are the
same height, assuming a smooth earth's surface and assuming an earth's
radius of 4000 miles, which is close when we take into consideration the

Keep the roar down, but am trying to figure what one would expect
the distance of a 440 repeater to be with 20 watts out, into a
Diamond Antenna up 50' fed by 7/8" hardline, 6 DBi of gain.
The user on the other end is using a base antenna, not sure of type,
but about 50' and cannot hear the
