What exactly is signal analysis? Web sites 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, I actually are in Virginia Beach, Virginia. It happens to be the most significant city in Virginia and as you might expect, has several TV stations close up 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 stations that I should be able receive inside 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, almost all of the channels are southwest individuals within 25 kilometers. Which means that most UHF/VHF antennas should work fine for us.
Not everyone lives in a large city area with lots of choices for local TV channels and where just about any digital TV SET antenna will do. When you are in a tiny town in eastern Montana, for instance, you might only be able to get four channels from two areas and then only if you use a huge online outdoor HDTV antenna attached high on a mast.
Antenna power is deceptive because antennas are couch potato and don’t actually produce any power. It actually refers to the antenna’s gain, which measures how much power of the transmitting antenna’s power your antenna can actually receive. The higher 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 kilometers.
It’s not a good comparison tool since range is sensitive to a number of local conditions between you and the transmitting antenna. Nevertheless, for the average consumer, it’s probably about the only specification that you will be able to compare.
TV stations transmit over UHF and VHF frequencies. To have the best chance at obtaining the most channels in your area, 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 1 or the other at your location. For most, a dual UHF/VHF TELEVISION antenna is the way to go 10Sharks.com.
You point a directional antenna in a single path in attempt to enhance the signal strength of a single station or set of stations in that direction. In case 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.
