What exactly is signal analysis? Websites like AntennaWeb. org and TVFool. com give you the best shot at predicting what type of antenna you need before you buy. You give them some basic information about your location and their software will perform an analysis of the HIGH-DEFINITION antenna type that is most likely to deliver the best results.
By way of example, We reside in Virginia Beach, Virginia. It is the greatest city in Virginia and as you might expect, has several TV stations near by. In fact, I live within 10 miles of several stations and they all happen to be in about the same direction from my house.
To do an analysis, I entered my zip code into AntennaWeb. org. Its analysis revealed me that there are no less than forty eight channels from 23 channels that I should be able receive at my location. For each local TV channel, it lists the RF channel, its distance from my location, and the relative direction to the channel’s broadcast antenna. From my location, the majority of the channels are freebie southwest people within 25 kilometers. This means that most UHF/VHF antennas should work fine for us.
Not everyone lives in a huge city area with lots of choices for local TV SET channels and where just about any digital TV SET antenna will do. If you stay in a tiny town in eastern Montana, for instance, you might be able to get four channels from two stations and then only if you use a sizable directional outdoor HDTV antenna mounted high on a mast.
Antenna power is deceiving because antennas are unaggressive and don’t actually create any power. It actually refers to the antenna’s gain, which measures how much strength of the transmitting antenna’s power your antenna can actually receive. The larger the gain, the better the reception. Gain is also a complex topic so most antenna companies choose to publish the product range of the antenna in miles.
It’s not a good comparison tool since range is sensitive to a number of local conditions between you and the transmitting antenna. Having said that, for the average consumer, it’s probably about the only specification that you will be able to compare.
TV stations transmitted over UHF and VHF frequencies. To achieve the best chance at getting the most channels in your town, you should choose an antenna with both UHF and VHF capability. The only time you would want to choose an antenna with just one frequency range capacity is when you only have the choice of one or the other at your location. For most, a dual UHF/VHF TV antenna is the ideal solution 10 Sharks.
A person point a directional antenna in a single path in attempt to increase the signal strength of a single station or arranged of stations in that direction. If your stations are far away in a specific direction or you will find a lot of interference, a big directional outdoor TV antenna would be the right choice.
