This Boscam 5.8GHz Cloud Spirit Antenna Set is designed for use in FPV applications. They are a refined version of the traditional "clover-leaf" FPV antennae but are now housed in a RF transparent dome. This offers better looks and excellent protection. They are bendable, easy to setup and use standard SMA connectors. Package comes in a pair that includes one antenna each for transmitter and receiver.

The manufacturer did not wash off the active flux after soldering, so the copper antenna elements started to corrode (it looks like a green substance, maybe flux contained sulfuric acid - electrolite which provides electricity and reduces signal strength).
Antenna elements are chaotically bent - i guess manufacturer made a fine tuning that way.
The plastic cover is extremely fragile.
There are some photos in the "FILES" section.
I recomend to wash off the flux and corrosion with isopropyl alcohol and water to have better results. Do not use acetone and butyl acetate - it will melt the plastic cover.These are brilliant qaulity nice and neat and very tough
However there not a must have for fpv
They are a cheaper alternative to immersion fatshark antennas but there half the price for a reason there only half as good. For park flying close range or even close range film taking there good but for long range spend the extra dollar on immersion fatshark antennas.HobbyKing sent me RP-SMA when I bought SMA!!
"Thank you", HK.free shipping and at platinum member pricing decided to give it a shot. They have been great so far and video is great on my IMRC 600mw.Must have for FPV 5.8GHZWorks good with the Teleporter. Range is clear near 400m with the 250 mW Transmitter. A usefull Thing.
