NettetHam Radio Satellite Antennas. One of the cool things about working the FM satellites is that you don’t need a lot of sophisticated equipment. A couple of HTs—or an HT capable of duplex operation—and a handheld, dual-band Yagi, as shown in the figure below, will do. One of the most widely-used antennas for satellite work is the Arrow II ... NettetThe batwing antenna is a turnstile antenna with its linear elements widened as in a bow-tie antenna, again for the purpose of widening its resonant frequency and thus usable over a larger bandwidth, without re-tuning.
