5.8 Ghz receiver (Boscam RC 305) + 200 mw 5.8 Ghz Tx (Boscam TS831) + right-handed circular polarization antennas = $40.98 including shipping
eBay search for "
Boscam FPV 3km 5.8G 5.8Ghz 200mw Wireless AV Transmitter Receiver TS351 RC305"
Note: Make sure you buy the version with the right-handed circular polarized antennas.  They are important for longer range and less video dropouts.  The left picture above, of my Tricopter, shows the transmitter antenna that I bought as part of the above package.

I have bought several video transmitter and antennas from Surveilzone.com, with very fast delivery.   They have the best price I have been able to find on the TS832 video transmitter and antenna.

Note: The Boscam 600 mw specification for the TS832 from Boscam is probably wrong.  Tests have shown that the TS832 actually outputs < 300 mw of power.  The Boscam 200 mw version does output > 200 mw, so it is accurately spec'ed.  I have also found reviews on-line that state the best Boscam transmitter is the 400 mw version.

I have several 5.8 Ghz receivers and FPV headsets:

- single RF section receiver; Boscam

- dual RF section diversity receiver; xxxxxxx

- headset; Quanum FPV Goggle Set

- headset with DVR and diversity receiver; Eachine VR D2 Pro

I have begun to record airborne video with the VR D2 Pro.  Here are some video(s) below; more will be added over time.

If you want to pay a little more and get a strong output signal, Immersion RC has a 600 mw Tx that has been measured at > 700 mw. There are many transmitters and receivers available, but the I have listed here the ones I have used.
