What is the difference between UHF and VHF signals?
HD television can be easily categorised into two groups in terms of the signal frequency. Ultra high frequency (UHF) are mainly composed of channels between 14 and 69 and they are typically broadcast anywhere upwards from 300 mega hertz. VHF (very high frequency) are composed of channels from 2-13 and the channels lie between 30 to 300 MHz.
Your location will also influence the kind of channel set caught by the antenna in your home. There are many antennas available in the local market which can catch more these two kinds of groups. Anyway it’s a wiser idea to have some knowledge about which local T.V stations fall in which frequency group before you finalise your purchase of a digital antenna. Calling the local T.V station will give you this idea.
How do station locations influence your choice?
The signal source location is super important when you are looking at digital antennas. There are two types of antennas; uni directional and multidirectional. Unidirectional antennas have a fixed long arm which will usually automatically point towards the direction of the nearest HD signals. These antennas are far reaching but their reach is limited to one direction only. If you live in a big city you should buy a multi-directional antenna which will point towards multiple signal stations.
Point to remember
Always purchase your antenna from a manufacturer who will give you a full refund in case you want to return it. Remember to fix your antenna in a firm position using sticky patches or attach rubber feet to your indoor digital antenna.
