Hi!!!

What is approximately range of 500mW video transmitter, with normal antenna and what is the range with circular polarized patch antenna!

I have 500mw Brown Bag Kit http://www.blackwidowav.com/brownbagkits.html , and I did not yet test the range of my transmitter and receiver!

thanks, from Croatia

How long is a piece of string?

Your range will depend on on number of factors, including the flying environment (ie city or country), methods of installation, altitude, etc etc. Get a GPS and run some tests. Play around with different mounting locations and you'll be amazed at how the max range can change.

Oracle Diversity and dual RX is a good option for dual antennas on RX (base station). High power (13dbi) patch antennas work best for long range flights. These are directional so not much good when you find yourself flying behind them. If you're not planning on flying 1+ miles from RX then 3dbi rubber duck antenna may be a better option as they do not have to be pointing at the tx.

I run diversity with a patch and 3dbi rubber duck antennas. Works great.
