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.

16.8    CML  KP 17-element Yagi ... ( YA17KPPD)
15.3    CML  M Squared 11-element Yagi ... (915x-ISP)

14.1 *  CML  True Gain 10 -element Yagi ... (TG-Y915-14)
13.0    CML  KP 9-element Yagi ... (YA14KPPD)

* ADD  0.2 - 0.3 dBi Gain to the True Gain Antennas to account for coax loss.
TG-Y915-1x antennas were the only tested models with coax pigtails.
Thus, only TG antennas gain measures included normal cable losses.

 * 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.
