The name says it all: True Gain® Antennas. The true gain of each antenna is what is listed on the specification sheet, not just some projection, estimation, or illusion. With True Gain Antennas, you get ...All the Signal.
Unlike most competitive products, True Gain Antennas are extensively tested at our own far-field antenna range and RF labs. Computer simulations and other industry shortcuts are not good enough for us, or our customers.

Motorola specified its 6 Mbps Canopy range with two 9 dBi panel antennas at 10
miles.
Note
that in woodlands that same -116 dB system loss would yield ~1/4 mile Theoretical
Range (less after a rain). In woodlands, changing one antenna to 17 dBi would
add ~ 100 meters, 200 meters if 17's are used at both ends.
