Cp antennas for the control system

[lobstermash]

In spite of all of us spending lots of time and money on antennas for the video system, the best things we do for the control system is position the rx's 2 antennas at 90 degrees and perhaps use a patch.

Has anyone used cp antennas on the control system? I'm curious about how it'd affect range, taking into consideration that the data transmitted between a control system tx and rx are minuscule. Would orientational reliability offset the slightly lower gain of a sp on the rx?

i dont think that you need cp antennas for your 9X/UHF/FM system. Just make an one element yagi. That works just fine.

Do they make a patch for 72mhz? I don't CP antennas would help, linear travels better anyway.

i dont think so since the antennas are not changeable and it would have to be huge!! Lower frequency=smaller antenna!

Haha, yeah, it'd look something like a space satellite dish for 72Mhz! Even for UHF cp antennas would be too big.

Linear travels better, but I'm thinking about how the radiowave delivers information. For low data applications, the information carrying part of the signal is tiny - as the amount of signal received decreases (generally with distance), the chances of the information itself being received decreases. CP antennas are much better at transmitting the entire signal between two points with the smallest signal loss for orientation changes.

I don't know. Maybe I'm over-thinking it.

I think the last. With all the cool stuff people do it should have been done already

Damn! I want my hover board!

My head hurts. I'm going to go down into my garage and sand on some foam like a caveman.

I've got an unfair advantage. It's morning here and I've just had my coffee. Don't talk to me at 3pm...
