Omnidirectional 27MHz marine deck mount antenna, 27.68-27.98 MHz, 25W, UHF male PL259, 4.5m cable, 2.1 dBi - 2.1m
The ZM21-27 omnidirectional marine 27MHz deck mount antenna, is suitable for 27MHz communications whilst at sea. The ZM21-27 marine 27MHz antenna is tuned for maximum performance for the Distress, Urgency and Safety Calling 27.86 MHz and 27.88 MHz frequency allocations. The ZM21-27 marine HF antenna requires either a MM1 white nylon fold down base, MM2 stainless steel fold down base or alternatively you can mast mount the ZM21-27 HF marine antenna utilising a MMA mast mount adaptor with 2 x EB1-SS parallel mount clamps. ZCG recommend waterproofing your terminations utilising two layers of amalgamation butyl rubber and a single external layer of uPVC tape to ensure no water ingression into your connector joints. The ZM21-27 27MHz marine antenna should be orientated in a vertical polarisation whilst in use and completely laid flat whilst the vessel is being transported on a trailer to avoid contact with overhead infrastructure.
