It would be a bear to get it mounted on the towers . I asked more out of
curiosity. We use omni antennas as a fall back if a sector fails. Since we are
converting existing towers and deploying new towers with 450i 900 I would love
to run4 90 degree sectors with an omni above or below them. 10mhz channels on
the sectors and a 5mhz on the omni. We try and have redundancy on every AP and
backhaul I just have not settled on a good way to do it with the 450i 900 yet.

What Chuck is talking about would I guess be similar to this:

I’d hate to see that thing twice as big.

I'm imagining a 900 MHz yagi arms race with 6' length and a whole cast iron
bathtub behind the mounting for rear/side shielding.
The rf armor guy will probably sell a kit for $899...

Roughly double the size for every 3 dB improvement in gain.

Chuck how big would an antenna have to get to get up into the 9 or 10 dB range?

Depends on gain. 6 dB would probably be 5 feet tall.

How tall would something like that be?

I did a nice 6 dB H pol omni a few years ago. Never released it. I could do a
dual slant 900 omni. It would be probably 8 inches in diameter.

9dB is what we have now.

Hello:

I recently just tried to get an ODH9-9 900MHz Horizontal Omni, to find out they
quit making it. Every few years they have to be replaced because the internals
rust out, but we are used to identifying the issue and replacing them when it
happens.

So, does anyone have any NIB ODH9-9 omnis they are willing to part with? Or am I
going to have to switch to Amphenol?

Regards,
Chuck
