Ok, ok, I lied! This isn't about sex, but since I finally got you to look at my post... I am trying to figure this out and am hoping that someone with wifi experience would check my work.
I am trying to mount a permanent antenna array on my roof that I can plug my P2V+ controller and repeater into and then fly FPV from inside my home.
Here's what I am thinking... Using a standard p2v+ (with the OEM 2.4 ghz repeater and 5.8 ghz contoller) along with: two 2.4ghz sunshans amps; two 5.8ghz sunshans amps; 2 6db antenuators; and a 100' of rg58 cable (because its cheap and flexible) to build a 50' run to a rooftop fixed antenna array to achieve significant fpv and control distances.
I used this calculator: http://www.saarsham.net/coax.html to determine db and power loss over 50' of rg58 cable.
I would connect the attenuator between the repeater and the 1st 2.4ghz 2000mw amp and then run 50' of rg58 to a second amp of the same power/frequency. This second amp would output through an omni-directional antenna. Supposedly, at 2.4ghz I would get 91mw entering the rooftop amp, which should be adequate. The bi-directional "pre-amps" in the sunshans amplifiers should make up for the 13db loss along the 50' cable (at 2.4ghz).
Likewise, I would connect the other attenuator between the 5.8ghz contoller and a 2000mw 5.8ghz sunshans amp, then run another 50' of rg58 to a second amp of the same power/frequency with 8 mw entering the rooftop amp (after a 24db loss through the cable). Again, this second 5.8ghz amp would output to an omni-directional antenna. I think that with a one-way 5.8ghz signal coming out of the 2nd amp that you would have sufficient gain to control the bird at distance - even with the 24 db loss along the cable.
With both the 5.8 and 2.4ghz antennas, I assumed a 1.5:1 swr omni directional antenna.
I have the bird and the amps, otherwise I would just switch to another frequency. I'd really like to get this setup (or similar) working. I know virtually nothing about microwave technology.
Now, wasn't that way more interesting than sex? LOL
