Can anybody provide a bit of advice?
I’m planning a point-to-point link , 7 mi (11 km). Excellent LOS.
I was considering using:
2 RB912-outdoor
2 Laird GDDA5W-32 dual polarity
My math comes up with a -44 rcv signal.
Is there any reason NOT to do this plan?
Thanks !

take smaller antennas 23-26dbi will be fine
like that one:

or

it is enough and you will get full throughput with RX -62 - 64db (need free channel)
with reduced tx-power “all rates fixed” 12-14dbm
Agreed. The link would work fine with a lower gain antenna.
The only way I’d use something that strong for a link that short would be in a horribly noisy area, and I’d still turn the TX down quite a bit. Ideal signal is in the -50s to -60s, I’ve got plenty of 54Mb links @ -75.
We mostly using high quality parabol antennas for PtP links even for short links with reduced power settings.
So you have less noise form back and sides.
You can run two antennas back to back with same frequency.
So do we, but a $300, 32dBi dish?
Jirous has a few options, much smaller dish, radome included, still high gain.
if you want to reduce the signal quality , change the Tx power manually , it’s better than changing the antenna which costs mony and time.
I apologize for the late reply to all. Thank You!
This link did turn up nicely, -49 - 94/99 CCQ.
