There are several things to be considered:
\nType of antenna (Length)
\nGain of the Antenna (As more the antenna can “roll”on the boat position, as less the gain should be.)
\nSWR = Standing wave ratio<\/p>\n\n\t\t
There is a simplified rule for the antenna range:
\nIf you have 3 db gain, you can transmit about 1,15 x the height of your antenna
\nGain of the Antenna (As more the antenna can “roll”on the boat position, as less the gain should be.
\nMaximum gain is about 9dB<\/p>\n\n\t\t
There are some very simple rules:
\nKeep the antenna and the antenna cable away from flurouscent
\nRoute the antenna cable at least 1m away from other radio antenna cables, deoth sounder transducers, other antennas
\nUse only coaxial cable of good quality, like RG 213 or Aircell 7
\nDo not extend cables if you don’t need to
\nDo not coil coaxial cables, store it in a random jumble or a figure – eight to prevent magnetic anomlies<\/p>\n
