Mobile dual-band monopole comprised of dual stacked ˝ waves on UHF and a 5/8 Wave antenna for VHF band. Careful design combining the UHF collinear coil with impedance matching plus length adjusting coil in base produce good dual band gain in the amateur radio 2 meter/70 centimeter bands.
Motorola (NMO) base with enclosed impedance matching coil hermetically sealed within. Tuneable to near perfect 50 Ohms to provide a 1.1:1 SWR at center frequency, with proper ground plane. Excellent for commercial and amateur radio usage for years of use under tough conditions. Tuneable Range 140-152 435-455 Mhz
