Up to 3x the distance of the stock antennas! This kit includes: 3 helix antennas conveniently installed on a single board, one 3d printed mount for the antennas, and 2 mmcx to rp-sma female cables.
The 5.8ghz has been increased to 14.5dBi so it’s quite directional with 38 degrees beam width. The 2 2.4ghz helix antennas for RC control are 10.5dBi and have a 55 angle degrees beam width.
It comes with 3 u.fl cables to rp-sma female and and a plastic mount that clips onto the metal handle of the radio.
With linear antennas, as soon as the transmitter antenna is away from the matching angle of the receiver antenna you incur losses in dbi. The further off axis the higher the dbi loss until the transmitter antenna is at 90 degrees off when you get the maximum -26dbi loss. With circular polarization however, no matter what axis the transmitters antenna is placed at, the circular pattern still matches the receiver so no losses are incurred at all. This gives you much more penetration through trees, behind obstacles and more.
This sku does not include the controller, or the installation. Only people with experience should attempt the install on their own.
