RF Wireless Cables

Choosing a cable for your antenna is straightforward. We offer three types of high-quality cable (shown below in bold). We strongly recommend best practice as follows:

  • Use ONLY waterproof cable.
  • Do NOT use 'lossy' cable (RG58, RG174) unless you want to lose some signal,  perhaps  to meet maximum radiation of 20 dBm as EC regulations require.
  • ALWAYS use heat shrink and self-amalgamating tape over all connectors to seal cables from water ingress. 99% of antenna problems are because water has got into the antenna cables.
  • Keep antenna cables as SHORT as possible. 5 metres of type 195 loses 3 dB, i.e. 50% of the signal. Use Power Over Ethernet to get the radio very close to the antenna and use a short antenna cable if possible
