Really? Why is that?

IBcrazys does not know himself why, apparently the lawmate does not handle the fact that the antenna GND connects to the active element, but it applies only to the cloverleaf and the : Skew-Planar Wheel

Some Fox receivers are poorly made and give crappy results. But a good Fox Rx with saw filter mod will give the same results.

One drawback of the Lawmate Rx: not compatible with the latest IBcrazys antennas
One advantage of the lawmate: small and sma plug.
I looked into the SAW filter mod... no thanks, the vimeo tutorial guy went thro hell to melt of the solder.

I was thinking if I got the 1W lawmate transmitter and used my Sunsky receiver will that work?

Yes, maybe not all the channels will match but some will and 1280 Mhz included

It's pronounced Caveman...
Just wanted to say the AGL filter seems well built, and although it looks flimsy, it survived a 50+MPH (GPS) crash with no apparent damage, with the lawmate dipole attached. Can't comment on it's effectiveness, except that I had video and rc control inside my car from 2KM while ground testing. Once the mud dries up I hope to do some testing in an empty valley using a fire-trail as a crash-zone/landing strip for distance testing.

Thank you.

I was looking through the book and thats what I got from the listing. I'm glad you corrected me so I know I want channel 9 and not 10.

Well my latest Sunsky order arrived today. Out of curiosity I also ordered one of these 1.2 GHz antennas to keep as a spare for testing purposes.

I figured they would be similar to the ones in the kits but to my surprise their actually much smaller and lighter. I decided just for the hell of it I'd hook em up to the new Tx to test and once again I was surprised! Compared to the stock antenna this smaller one consumed on average 1W less power on the 800mW Tx's!

From what I understand, having a lower power consumption means a better VSWR, correct?


EDIT: Also the these transmitters are different to the previous ones I've ordered, they have a connector on the side of the transmitter rather than the 4 wires being soldered directly onto the board.

was the connector a direct fit ?
Did you do a range check to check if there is a real improvement ?
whats the weight of this antenna ?

The stock antenna weighs 26g and this new one weighs 9g. The connectors are the same and I have no idea about range. I will do some more testing later.

Is the bev rc 1.2 ghz patch antenna compatible with the sunsky receiver in terms of the connectors? Does anyone have it, do you recommend it?
