I have no idea what you are trying to say.
Take your "H", turn it 45 degrees. You now see "existing" "H" -3 dB less.
Take your "V", turn it 45 degrees. You now see "existing" "V" -3dB less.
Since the antenna on the far side of you in a PtP or PtMP scenario is
also a 45deg matching slant, there is no loss in received signal from
that transmitter.

I’m not sure that’s true unless the AF does some sort of noise
cancelling algorithm, which maybe it does. But I don’t see where the
antennas alone accomplish that. Yes, +45 would see V at –3dB, but it
would also see H at –3dB, and assuming they are uncorrelated, the
addition puts you right back where you started.

Rockets don't decide the slant/linear. The antenna does. So
those "HV Rockets" on the 45* antenna aren't HV at all.

I see I’m not ‘splaining myself adequately
On a given tower, if I have some rockets (H/V) and I use a 45
degree antenna, I should see additional S/N of x (3dB was my
guess) between the two systems.
While that +3db would be welcome, I’m not counting it.

Radios are different, but slant vs pol won't get you different
signals.

Looking to put in an AF5X with the 45deg slant antennas.
Was curious if we would see any additional link
improvements over the H/V Rockets.
I’m just assuming we won’t to error on the side of caution.

if you have any links with oddball H/V signals, dual slant
would level them out a bit to be about the same on each
polarity.

Looking at using AF5X for a link with the 34dB 45* slants
What kind of improvement would you expect to see over
standard V/H polarization? +3dB? +6dB?
Thanks!
