Thanks. I’ll have to do more testing at specific frequencies to be
more accurate but so far we have seen improvements in reflectors that
can’t be explained by anything else in both high and noise
environments.

Depends on the design.
If the gains are the same, then go to F/B ratio to decide.
If approx equivalent then check the look of side lobes.
Nothing magic about parabolas. They are just highly characterized and
easy to do.
A good patch array can be just as good for some applications.

So Chuck, what’s your opinion? Parabolic or reflector that the
manufacturers spec out at approximately the same gain?

Gain of a parabolic reflector:
=10*LOG((0.55*((3.1415*Dia/Lamda)*(3.1415*Dia/Lamda))),10)
.55 is the efficiency factor. Most of them range between .55 and .60
Diameter is in inches. Lamda is in inches.

If you are talking about the 2’ dishes, their gain in 5GHz is the same
as the KP reflector. We may test that but honestly, between the price
difference which is more than $100, the weight, and the complexity, it
would have to be significantly better and I doubt it is.

They still work down there, just lose a couple dB. Their better
rejection makes up for it.

Most Jirous antennas aren’t good for under 5.4GHz though. We started
using them after being told more than 2 years ago they would have
updated nose cones shortly. I’m still waiting.

Jirous makes antennas with good patterns.

We love the KP Performance antennas for the CPEs, but haven’t used
them yet for backhaul. Have you been using them for that as well?
We were worried the wider beamwidth would catch too much other noise.
Or maybe that hasn’t been an issue?
Thanks,

Right now the best antenna we have tested at 30dBi has been the KP
Performance antennas. We will be testing the RF Elements antennas
next.

We have traditionally been using the Arc Wireless 30 dBi 5 GHz
parabolic dish for our shorter backhaul links when using 5 GHz. The
have been OK, but we have a tough time getting them and the radomes
from time to time. We are in that situation again. They are priced
quite competitively, and seem to do the job, however we are looking
for options since they are so spotty to get ahold of. We have messed
around with the Ubiquiti RocketDish for CPE connectorized radios, but
haven’t tried them out for backhaul as of yet. The specs appear to be
very similar and I expect they’d perform about the same other than the
N-Type vs SMA connectors. Anyone have experience with both of these
dishes? Or is there a better alternative that we should be looking
at in the $120 range (dish only)?
Regard,
David Coudron
