Sea Tel 2400 Dual Band C/Ku 2400 Dual Band Technical Specifications
18-11
EAR Controlled - ECCN EAR99
18.2. Cables
18.2.1. Antenna Transmit & Receive IF Coax Cables (Customer Furnished)
Due to the dB losses across the length of the RF coaxes at L-Band, Sea Tel recommends the following 50
ohm coax cable types (and their equivalent conductor size) for our standard pedestal installations: These
cables must be fitted with 50 ohm Type-N (M) connectors at each end.
Run Length Coax Type Conductor Size
up to 75 ft LMR-300 or RG-8 18 AWG
up to 150 ft LMR-400, RG-213 or RG214 14 AWG
up to 200 ft LMR-500 or LDF4-50 Heliax 10 AWG
Up to 300 ft LMR-600 6 AWG
For runs longer that 300 feet, Sea Tel recommends Single-mode Fiber Optic Cables with Fiber Optic
converters.
18.2.2. Multi-conductor Cables (Customer Furnished)
Due to the voltage losses across the multi-conductor cables, Sea Tel recommends the following wire
gauge for the AC & DC multi-conductor cables used in our standard pedestal installations:
Run Length Conductor Size
