G7fek vs g5rv
WebPart of the problem may be the feeder composed of window line and coax. For the G5RV, the window line section is used to transform the impedance to something that is better matched to the coax at 14MHz. The fan dipole is inherently a decent match to coax, so the impedance transformation is unneeded and undesirable.WebG5RV Antenna The G5RV antenna, with its special feeder arrangement, is a multiband centre-fed antenna capable of very efficient operation on all hf bands from 3.5 to 28 MHz HF portable antenna - 40 to 6 meters Homemade 40 through 6 meter HF portable multiband antenna, an aluminium antenna construction article, with plan, drawings and photos
