Keri recommends the following cable gauges:
• AWG 18 allows up to 500 feet
• AWG 22 allows up to 200 feet
• AWG 24 allows up to 100 feet
2.3 The Exciter’s Antenna
The EX-10 Exciter’s antenna can have a gain of no more than 8.1 db, per FCC regulations. For best operation the coaxial
cable between the antenna and transmitter should be kept as short as practical. We recommend no more than 10 feet.
Longer coax lengths than this will reduce the operating range of the system.
NOTE: The cable seals in the body of the Exciter enclosure are designed to accommodate one cable. Forcing more than
one cable through these seals compromises the weather-tight seal, allowing water to enter the body of the enclosure.
