I'm looking for a 900 mhz circular polarized antenna. Any thoughts?

Thanks!

I use this one. Works ok. If you go to their website they have a list of distributors and just find one near you.

Here they are in the USA but they cost about $80 before shipping, about double what the usual linear one goes for. Too bad, for the 2.4 band a circular is only like $5 more.

They have RH and LH if you have a preference.

I paid the price to get the size advantage, they are tiny compared to linear patches. Some thing I had to consider when I have three rx's on the GS. Also remember that after the std 3dBi loss they will not offer any more range than a 3dBi omni.

You mean 3 video Rxs? Diversity? If so how do you do it with 3 rx's?

There is a picture in my blog, but basically use Eagle Eye's and Oracle to pick between the best of the two patches and the omni. Oracle picks the best patch and EE picks between that and the omni.

Sorry to drag up an old thread but I built my own (probably cost me a total of 10 to build the pair including cable and crimp connectors).
