But B11s are, in the end, still half duplex. Other than the fact that
you end up with a licensed link, it will not perform like a traditional
licensed 11 GHz.

another thing, the B11’s can get up to 480Mbps of real throughput in a

Just $1,200+ more per end than an AF11x.
You could buy a pair of Cisco SFPs for that savings! At list price! ;)
(Yes, I understand business case vs product cost, just ribbing you a bit.]

I haven't bought B11s, just while scouting for options, I *COULD* do
B11s. I could also swap them out later for something else like an
AlfoPlus2.
Why would I do a B11? Cheapest 11 GHz link with an SFP.

*nods* I asked about going from a 3' to a 6' SHP dish, no go.
That said, I've got a couple paths in HFT central where I can
still do B11s. :-)

My finger clicked send before my brain.
Interestingly, a RadioWaves HP2-11 has 60dB f/b ratio and is a
Cat B. While a HP3-11 has 62dB f/b and is Cat A. The
VHLP800-11 has 59dB f/b and is Cat A while being only 3"
smaller in actual diameter vs the HP3-11 (35.5" for a "2.5"
foot antenna, vs a 38.4" 3 foot). But a bit weaker f/b ratio
than a HP2. Both are shrouded. I don't get it. I think there
may be something else like main lobe beamwidth, too.
The problem with all this Cat A vs B stuff is it really
doesn't matter anymore in congested areas. I had Liz look for
a 56MHz channel on a path. She said nope. I said, OK, what
about changing the 2' end to a 3'. She still said nope.
Polarity, antenna size, etc., nothing mattered. Out of
channels is out of channels. Good luck with those funky B11's.

Yes. Not a size requirement, just a suppression
requirement. It's just what size of antennas normally meet
those requirements.

IIRC, the classes are about front to back radio and
sidelobe suppression.

Does anyone make a 2 foot Class A antenna for 11 GHz?
Or is 3 foot the minimum.
Does anyone make a 1 foot Class A antenna for 18 GHz?
Or is 2 foot the minimum.
Is there a minimum distance for a 11 GHz link?
Thanks
Adam
