Incorporating some revolutionary concepts in antenna design, the Tomahawk Backfire antenna is a high gain, wide angle antenna draws from radar technology to optimise its performance. In doing so the Tomahawk backfire squeezes maximum performance into a unit less than half the size of similar antenna whilst maintaining an incredible 175° horizontal and 60° vertical fields.
Lightweight and headset-mountable, the Tomahawk backfire can breathe new life into your 5.8GHz FPV gear, giving it a huge boost in range.
Note: This antenna will work with both left hand and right hand circular polarized antennas.
Vertical lobe angle: 60°
Horizontal lobe angle: >175°
Power limit: 50W
Dimensions: 62 x 40 x 8mm (122mm length inc stem)
Note: The antenna should be orientated at approximately 45 degrees up to the sky for best performance.
Just checked that antenna yesterday for 3 flights.
It works well, but as any directionnal antennas, you need to point your plane with the antenna to get it working correctly.
It's easier to use when your plane is far away so you don't have to ajust the antenna position so often.
I recommend to use this antenna on a diversity setup, so that you always have the signal from an omi-directionnal antenna if you get out of the range of that one.
Overall quality is good, and it seems less fragile than a x.turns helical antenna.Just be aware that the propper orientation for this antenna is NOT like with most other patch antennas. You must orient the arrow on the antenna towards the model. If you do that, the antenna works wonderfully. I got lots more range and lots more tree-penetrating capability with this antenna than with the immersion rc cloverleaf antenna. Highly recommend.Useless antenna, no difference at all in my diversity system, went around and in between the trees at about 200 meters and lost almost full video reception, even tried facing the antenna the other way around with no changes at all, besides it produces so much noise that somehow when I place My radio close to it the screen on my transmitter gets crazy, overall a complete waste of money
