Ultra Slim Antenna

Because we use multiple cell phones in Trailhugger, we opted to use the Ultra-Slim antenna instead of the Cradle Plus. Like the Cradle Plus, it plugs into the amplifier and transmits and receives the cellular signal to cell phones or data cards in the vehicle, only it doesn't offer the mount. Like most wireless systems the signal is the strongest near the inside antenna and it degrades with distance. We've found that our phones get the maximum benefit from the system when within a foot or 2 of the inside antenna, but we're still seeing an increase in signal strength up to 4 or 5 feet away, which makes the system beneficial for both front- and rear-seat passengers when the inside antenna is centrally located.
