What kind of power source or batteries does this require??
Over the air (OTA) TV has been around since the advent of TV and was how most of us watched TV until the rise of cable and later, satellite direct broadcasting. So it always amuses me when ad copy implies it’s some new revolution. (Although I concede digital TV greatly increased the number of stations available.)
The term “HDTV Antenna” cracks me up too. An antenna is just a conductor, usually wires or metal rods, designed to resonate at certain frequency ranges. The roof top TV antennas or set top rabbit ears you might remember from decades ago, along with the telescoping rods on portable radios, are all antennas. A TV antenna doesn’t know or care if the signal it’s receiving is high definition, standard definition, digital, or analogue. Antennas are designed based on the transmitted frequency to be received (more accurately, the corresponding wavelength) and not the type of modulation used to carry information via those frequencies.
All that being said, I keep a cheap set of rabbit ears in the closet which work fine in my area when we have an occasional cable outage. If I were going to depend on OTA broadcasts for most or all of my viewing, a good external antenna like this one will perform better. But beware of range claims. That has more to do with the topography between you and the transmitting station, the power of the transmitter, and a lot of other variables.
Generally there is a table top base unit that requires a/c and is then hardwired to the mounted antenna. This powers the rotation motor allowing you to direct the aerial towards the transmitter.
Back in the 60’s we lived in the DC ‘burbs and had one for our color console which allowed us to pull in some Balmer stations.
Hi there. Here’s the manual. It doesn’t mention anything about batteries. The power supply is included though.
