I need a 60 meter transmitting aerial for a HF Shortwave service with 1kw Can anyone tell me where to get one =============================== == 60 metres ,hence freq is 5 MHz ? == Fixed frequency ? == What is desired operating range ? == What area is available to accommodate an antenna? If for a limited range I would put up a single tubular (guyed) mast with a non-metal top end and fit an inverted V shape dipole with a suitable length of twin feeder and a current balun/choke near the transmitter ,assuming the transmitter needs to see a 50 Ohms resistive load. The dipole would be 2 times 15 metres long with the twin feeder length 30 meters or a multiple thereof . Alternatively an inverted V dipole ,length 2 times 30 metres with the twin feeder length 15 metres or an odd multiple thereof. Your question is too broad , please specify purpose and operating freq/range of the transmitter. Frank GM0CSZ / KN6WH |
