Hello to all in the group.
I would like to ask all the antenna Guru's in the group for their
input regarding replacing a Hustler G6-440 Ant. with a Stationmaster
Ant. on a friends repeater. No,It's not that simple a question. Here's
where it gets involved.

I don't think you'll get too much Hustler-bashing in this group. Those are
decent antennas, and it might outlast the Stationmaster if the antenna must be
top-mounted on a tower. A Stationmaster lives longest if side-mounted with a
support arm for the top of the radome. Without it, they

Isolators work with transmitters only. That would do nothing for
getting signal from the antenna into the repeaters.
What you need is a diplexer. That is a low pass / high pass filter

filters, but that usually only has enough Q to

If the duplexers for each system are only 50 ohms at each receiver and
transmitter, then I should see 4 frequencies where there is a 50 ohm
load, and they are all different. Why would I need more than some sort
of phasing harness to connect the two duplexers to the single
transmission
I stand corrected!

How about taking the 16 bay, and splitting the harness in the middle and
feed a second cable for the additional repeater.
Two antennas on one mast, less insertion loss, with combining the 2

Or make the top antenna a Master receive and the bottom one transmit
