Creating the Dual-Band DBJ-1 So how can one add UHF to the con-ventional 2-meter J-Pole? First of all, a half-wave 2 meter antenna does resonate at UHF. Resonating is one thing, but work-ing well is another. The DBJ-1 not only resonates, but also performs

In the above example, VHF and UHF can be combined onto a single feedline using the specified crossband couplers. In the following example, VHF, UHF and 700/800 MHz are combined onto a single feedline: C B C B C FEEDLINE 30 - 180 MHz 330 - 520 MHz 740 - 960 MHz VHF UHF 700 / 800 SP0000-1151-11 CROSSBAND COUPLERS
broadband VHF/UHF set‐top antenna using the continuously resistively loaded printed thin‐film bow‐tie shown in Figure 1‐1. It featured a low VSWR ( 3:1) and a constant dipole‐like azimuthal pattern across both the VHF and UHF television bands.
Antenna Systems Chapter 18 VHF and UHF Antenna Systems A good antenna system is one of the most valuable assets available to the VHF/UHF enthusiast. Com pared to an antenna of lesser quality, an antenna that is well designed, is built of good quality materials, and is well maintained, will increase transmitting range, enhance
