WebJun 24, 2014 · 144 M H z ⋅ 3 = 432 M H z So, an antenna that looks like a half wavelength on 2m will look like 1.5 wavelengths on 70cm. Although the radiation pattern is different, the antenna impedance is the same, and so will provide a good match to the radio in either case. Keep in mind that handheld antennas are usually monopole antennas, like a vertical. WebOne everyday application where microstrip patches are used is in satellite radio receivers (XM and Sirius).
