Circular polarized antenna's aka "clover leaf antennas" are a great way to increase the performance of your FPV system. The circular polarization helps reject “multipath interference”, a problem that plagues standard dipole stock antennas. Proven to increase range and video clarity, circular polarized antennas have become the standard after-market 'essential' upgrade for modern FPV systems. This is a matched 3 leaf Tx to 4 leaf RX set with no cable length for a nice clean, direct install with SMA connectors.
Frequency Range: 900MHz
Cable Length: 0m
I try it with a 800mw tx, i test it at 1km, i never had black screen like with simple antenna!Don't waste your time with these. Worse than the rubber whip antennas. Spend a little extra money on the real ibcrazy antennas, you won't regret it.really really poor quality don't spend your money on things just couldn't arrive like they were shipped too big and not strong enought to be shipped like that i hope hobbyking will have more quality antennas in the future...Using these on my quad with 900mhz 200mw. About 3.5km range without video lostI was skeptical when I first purchased these antennas. I figured they would arrived mangled beyond recognition. I was pleasantly surprised today when I opened the box. Despite the box being dented both antennas were perfect.
I'm using these on a hk 200mw 900mhz tx and rx setup on 910. I only had time for one flight today but the range has definately increased. I need to play with it a little more to really see where the limit is but overall I'm impressed.The antennas arrived packed with bubble wrap and tape, not enough to keep them from getting slightly squished from shipping. Both antennas had a weak solder joint, a gentle tug and the wire broke free. I ended up scraping off the white glue and re-soldered the broken joints. Because of the great price I still think it's good value, just be prepared for a bit of DIY.
