ANTENNA SYSTEM Antenna for ship Required antenna element length Required antenna element length to achieve full perform ance varies according to the lowest frequency The lowest frequency Required antenna element length 1 6 MHz band 7 m 23 0 feet or longer 4 MHz band 3 m 9 8 feet or longer The longer the antenna element the better the antenna efficency Undeslreable antenna element lengths AVOID multiples of 1 2 A half wavelength for antenna element lengths since tuning becomes difficult L Antenna element length to be avoided m f Operating frequency MHz n Natural number n 1 2 3 L x l f2 xn Example At an operating frequency of 16 MHz avoid the following antenna element lengths 300 1 L X X n 9 4 18 8 16 2 1 m 39 inches For example if 15 m is selected for an antenna element length you have no problem in 1 6 25 MHz marine bands NOTE Keep antennas as far away from other objects as possible especially metal objects Antenna for land operation In some countries HF transceivers can be used for land mobile operation Ask your Icom Dealer for details since the radio law varies according to countries Refer to the AH 2b instruction manual for the AH 2b and AT 130 E installation to your vehicle Ask your Icom Dealer for details For land mobile operation on 4 MHz and above an optional AH 2b ANTENNA ELEMENT is available The AH 2b includes a sturdy tow hook mount system for holding a 2 5 m 8 2 feet stainless steel antenna element plus all the necessary hardware Connect a suitable antenna element for a coastal station To achieve full performance refer to Required antenna element length above
