Using the CX4A antenna is easy. First, find a suitable location on your yacht for installation. Make sure to use a 1.25″ commercial grade fixing base that the antenna fits into. Connect the antenna to your device using a low - loss 50 - ohm coax cable like RG - 213. This will help you get the maximum AIS range. When it comes to maintenance, regularly check the antenna for any signs of damage, like cracks or loose parts. Keep it clean to ensure good performance. Also, if you're using a long cable, pay extra attention to its condition. Remember, the cable isn't included, so you'll need to get one separately for the best results.
