Omni Gain-Beamwidth Relation - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

Hi all,
I am sure there must be a rule of thumb for the theoretical limitations of a gain & ele. angle relation. :?:
Lets say for an elevation angle of +- 70 degrees and 5dB omni possible?

thanks....

Hay,

you can roughly use this formula:

Gain[dBi]=10Log(30000/(BW1*BW2))
where:
BW1=E-plane BW in deg.
BW2=H-plane BW in deg. (360 for omni).
