SuperPass is an excellent antenna brand. The founder has several unique
patents in antenna technologies, that other antenna manufacturers would love
to get their hands on. There are several uique end results they offer... 1)
They tend to make it possible to make "shorter" antennas for similar gain.
For example with 5.x sectors, the make some of the most compact sector
antennas on the market. 2) They can make them very cost effectively, and
still have them perform well. These are great for repeaters, where there is
a low budget, and cosmetics and size is a concern, and closer to the ground
where less durable mounts are perfectly acceptable.
Now.... everybody cant be everthing to everybody. Just like anything else in
this industry, and Provider needs to define what they need and pick an
antenna that matches their specific need. SuperPass is NOT a MTI antenna,
they really serve two different market segments.
MTIs are EXPENSIVE and LARGE and HEAVY, the exact opposite of a Superpass
antenna. Of course the MTI is going to outperform the Superpass in most
cases. The MTI was purpose built to get optimal RF characteristics out of
the technology, and the trade off is expense, size, and weight. But the MTI
makes a VERY high quality antenna, if not one of the very best, from the
perspective of RF pattern, isolation, and sturdiness.
In 900Mhz, our personal favorite are the Tiltek sector antennas. We like
them because they have excellent front to back isolation and quick drop on
beamwidth edge comparatively, have rock solid mounting hardware thats easy
to adjust, and priced a bot lower than other high end antennas. We find
Winncom to be a good source for these, although I'm sure there are other
good sources. The Tilteks have both a Dual Pol and Single pol options. I
dont think its possible to buy a better antenna. Again, with quality, also
comes size. This is a 4ft by 1.5ft antenna at about 10db for 120deg. (Thats
