Re: [AFMUG] Class A and B antennas
If the B11's work for you, great. But we definitely use our FDD links to
haul hundreds of Mbps in both directions simultaneously, and with
sub-millisecond latency. It's naturally the best option where you're
doing rings with multiple borders/upstreams feeding the network.

They are half duplex but since they can combine transmit on both 40MHz
links, if the majority of your traffic is 1 direction, you end up with
more bandwidth for the same QAM. And again, $2K. So if you can get
800Mbps links, and can deliver more than 400Mbps in one direction, I’m
thinking that’s a pretty good value.
As for it being a glorified chipset, the Quantenna chipset was
designed to move lots of data and has a boatload of computing power.
And the next version is designed to move 10Gbps so I’m thinking
Quantenna is a little more than a WiFi chip. Yea, it’s half-duplex
but with 90% or more of my traffic moving 1 direction, who cares.
Considering this entire link cost about $6500 for radios and antennas
for a 50 mile shot, I’d say it’s a great value.

Yes, I'm fairly certain there isn't any way to use only one polarity.
I'm pretty sure that would have to be aggregate - but, since they are
half duplex radios, it should be able to do the full 480 either
direction at any given time (just not both directions at once...)

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.

Re: [AFMUG] Class A and B antennas
Yeah, the beamwidth too, forgot about that. And beamwidth is proportional to
gain. Gain is proportional to dish diameter.

Subject: Re: [AFMUG] Class A and B antennas
A couple of clarifications:
The VHLP800 (800 mm) is obsolete and no longer available - it was replaced by
the VHLP3-11W (3'). There was a lot of discussion about the difference between
A and B being sideline suppression and F/B and that certainly is true, but the
main difference between a 2', 2.6' and 3' is the main beam gain and beam width.
In order to meet Cat A at 11 GHz, the minimum size antenna that meets either
of these requirements is 2.6'. There's not a demonstrable difference in
co-polar patterns between these smaller antennas (Sentinel excluded of course)
and the ability to coordinate them (or not) depends on congestion and what's
within about +/- 30 degrees of main beam. There are major and demonstrable
differences between differing manufacturer's models of the same size. As
someone pointed out, the RW HP2-11 may be cheaper than RFS or Commscope, but
the cross-pol patterns pale in comparison and we have seen many instances where
a VHLP2 will coordinate where the HP2 will not.
Anyone that licenses a 2' or Cat B antenna needs to understand the liability of
doing so. In congested areas, it is certainly a risk that you may be required
to upgrade to a Cat A if another user cannot coordinate around your Cat B
antenna. All costs associated with this upgrade would be your responsibility.
Finally, I could mention that there are larger very high performance
(ultra-high) antennas (F/B > 80) that allow significant frequency re-use. Take
a look at Mt San Miguel near San Diego where almost every path is using
multiple 11 GHz frequencies and ultra-high performance antennas.

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.

This shows the problem. The purple test data shows that my 3 foot dish just barely fit under the CAT A spec for 11 GHz. My 2 footer just barely fit under the CAT B line.

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.

Re: [AFMUG] Class A and B antennas
H, can you clarify on minimum distance? I was not aware of a min distance on 11 GHz, but if its only 5 km, maybe that was just never an issue.

Re: [AFMUG] Class A and B antennas
A couple of clarifications:
The VHLP800 (800 mm) is obsolete and no longer available - it was replaced by
the VHLP3-11W (3'). There was a lot of discussion about the difference between
A and B being sideline suppression and F/B and that certainly is true, but the
main difference between a 2', 2.6' and 3' is the main beam gain and beam width.
In order to meet Cat A at 11 GHz, the minimum size antenna that meets either
of these requirements is 2.6'. There's not a demonstrable difference in
co-polar patterns between these smaller antennas (Sentinel excluded of course)
and the ability to coordinate them (or not) depends on congestion and what's
within about +/- 30 degrees of main beam. There are major and demonstrable
differences between differing manufacturer's models of the same size. As
someone pointed out, the RW HP2-11 may be cheaper than RFS or Commscope, but
the cross-pol patterns pale in comparison and we have seen many instances where
a VHLP2 will coordinate where the HP2 will not.
Anyone that licenses a 2' or Cat B antenna needs to understand the liability of
doing so. In congested areas, it is certainly a risk that you may be required
to upgrade to a Cat A if another user cannot coordinate around your Cat B
antenna. All costs associated with this upgrade would be your responsibility.
Finally, I could mention that there are larger very high performance
(ultra-high) antennas (F/B > 80) that allow significant frequency re-use. Take
a look at Mt San Miguel near San Diego where almost every path is using
multiple 11 GHz frequencies and ultra-high performance antennas.

Re: [AFMUG] Class A and B antennas
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.

My finger clicked send before my brain.
Interestingly, a RadioWaves HP2-11 has 60dB f/b ratio and is a Cat B. While a

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

Subject: [AFMUG] Class A and B antennas
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

Re: [AFMUG] Class A and B antennas
You might want to look into ETSI class 4 antennas. The Commscope Sentinel line is a good example. Pricey, and long lead time for shipment. But we're talking about antennas with 70 dB f/b ratio and specially engineered side shroud material for smaller side lobes/radiation pattern envelope. They are not common in the US yet due to lax FCC regulations (as compared to Europe, Canada) but you can get them.

s/radio/ratio And Mike, you're probably thinking of the Andrew/CommScope VHLP800, which is a shrouded reflector. A RadioWaves HP3 is about the same size. And cheaper.
