Build this AWESOME!  and TUNABLE! MIA Micro-FLIGHT FPV 5.8 Ghz Antenna  design, literally for 4 pennies!.

* Easy to Manufacture 

What you need:

(1) Typical SMA Connector and Coax to fit your FPV 5.8Hgz RX

(3) M2 x 10 mm Nylon screws 
(3) M2 Nylon Nuts

Important: Just make sure to align the center top penny to the delta pennies  below, concentric, before and during drilling. Use tape and a piece of wood as a jig, and take your time. 

 IT IS A FUN PROJECT, BUILD ONE NOW! 
Comments and questions welcome. 

If the Antenna does not seem to give you sharp image at a certain distance within the limits of your RF equipment, use a bit of trial and error and make tunning adjustments by tightening or loosening the nylon screws that hold the top and bottom sections. 

I did not have to do any tuning with my setup which  is set automatically by the VTX in my Mobula 7 quad to channel 1 frequency 5865 Ghz.
