Due to the loss 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. Type N male
connectors installed on the cables MUST be 50 Ohm connectors for the center pin to properly mate with the
female adapters we provide on the Base multiplexer panel and on the adapter bracket mounted inside the
radome next to the breaker box.:
