I am trying to determine what the best transmitter antenna is for this transmitter: To pair with this receiver: Application is for an ultra high speed (4kw, 1.5 lb) quadcopter (170 mph+). I need something that will allow me to do high speed passes without losing signal to set the defacto world speed record for 250 quads. I'm not clear if this receiving antenna is just linearly polarized or not from the listing. My first thought is to use a circular polarized bluebeam omni (since I will be maneuvering and switching between hover and fwd flight modes) but not sure if that will work well with this receiving antenna? I'm an aerospace engineer and have this quad flying beautifully but know very little about RF and need some serious range to exercise this quad!

Discussion Correct Transmitter Antenna For Patch Receiver Antenna 1.3 Ghz FPV Equipment.

Whether you’re a radio control fanatic or RC novice we have everything you are looking for! Radio Antenna. Futaba ANT8 Transmitter Antenna FG Series FUTANT8. ImmersionRC 5.8GHz SpiroNET 13dBi flat patch antenna. Patch antenna the antennas on the transmitter and the receiver need to be of. 5.8GHz SpiroNET patch.doc.

I am currently flying a lower powered version of this quad with 600mW 5.8Ghz system and still losing signal on passes, so this is planned as a huge upgrade both for dialing in the lower powered test bed and for use on the final high powered quad. Any help/input would be greatly appreciated! Are you planning on flying to the moon? Just going to 1.3 will not solve your problems - for starters 1W is waaaaaaaaay more Tx power than you need on 1.3 for what you are planning to do - I have done 10km with 200mW and Omni antennas on each end with crystal clear video.

600mW 5.8 is probably causing you more problems with reflections than it's solving and on 1.3 1W the problem will only be 10x worse. 25mW on either frequency is plenty for all ~500m LOS flying with quality Omni antennas and quality Tx/Rx's. Oh and don't even bother tying to use that Tx if you are using 2.4 RC, you will be lucky to get 50m before you failsafe. 433MHz control is a must on 1.3. And yes, that patch antenna is indeed linear, I have personally used one of those with a 200mW Tx to fly 20km and I have used it to watch someone else at 50km away.

Here's what you do: Get a good quality VTx (tramp/unify etc) with a clean power source, good antennas (triumph/ spironet) and a good diversity receiver (Laforge/true-d/clear view) and pick an unoccupied frequency and your video should be much better, especially up close. Also keep the Tx antenna as far away from other objects on your quad as possible. Thanks for the response.

I am flying above a big grassy field bordered on one side with a steep hill and on the other three sides it drops off (it's a plateau). Could it be the hilled side that I've been standing next to causing reflections? Talent Dress Up Games.

Your example doesn't sound right. The math says absolute best case theoretical with dipoles on both ends nets about 6km with 1.2 and 200mw. What RX where you using? I keep hearing people touting HUGE range on 1.2 with onmi and I am just not seeing it on my end. Thanks for the response.
