The maximum cable length that can be utilised by a GPS ntp time server antenna is dependant on the gain of the antenna and the quality of the coax cable utilised. TimeTools provides two types of antenna, a patch type GPS antenna and a pole-mounting type GPS antenna.

TimeTools NTP s5100 pole-mounting antenna has a higher gain than the patch type antenna, so can utilise a longer cable length. The gain of the pole-mounting antenna is 35dB, while the gain of the patch type antenna is 27dB.

The maximum cable distance for the patch type antenna are as follows:

Coax Cable Type Maximum Cable Distance that can be utilised
Standard RG58 Coax 20m (25m overall)
TimeTools Low-Loss Coax 25m (30m) overall

The maximum cable distance for the pole-mounting antenna are as follows:

Cable Type Maximum Cable Distance that can be utilised
Standard RG58 Coax 30m
TimeTools Low-Loss Coax 50m
TimeTools Ultra-Low Loss Coax 100m
