This month I'll finish the overview of UHF antennas I started in December's column. In addition to the overview, I'll describe how Andrew Corporation tests their UHF TV broadcast antennas without a test range and offer some observations on beam steering and differential gain in antennas.
Wireless cable is a rapidly growing area of TV broadcast transmission.
I'll update you on the latest developments. Last month I discussed UHF panel antennas and described the trade-offs involved in using them. Top mounted UHF slot antennas are much less complex to install with less chance for error. They can also provide excellent omni-directional coverage. Based on my observations, I'd guess that top mounted slot antennas are the most common full power UHF antennas in use in the U.S. today.
