next level is the ELITE 3Db gain antenna wich increases the overall range of a radio system.
Best on the market is the CAK-70 antenna with it’s built-in ground plane.
this one is used by most pro racing teams all over north America.

The primary role of an antenna is to transform electrical energy into electromagnetic field
with minimum loss.
Remember a good and reliable feed line (coax cable ) is critical to carry the signal from the radio to the antenna
and that a bad radio antenna can anhihilate your entire radio system performances
if improperly installed and tuned.
