TV signals through the structure of your home or other building. That typically translates to a less powerful signal and poorer wedding reception. An outdoor TV antenna can be larger and can achieve line of site with the sending antenna with no items in the way.
Some disadvantages of an outdoor TV antenna include a possibly complex set up and longer cable runs. If you want the best TV reception in your area and if you’re either trying to cut the ties with your cable company or you don’t have the choice of cable connection TV, then an outside TV antenna has the best potential for meeting your expectations.
TV antennas and antennas on the whole are difficult to understand. You could place the same digital antenna in two different locations and get vastly different reception results. That means that the performance of any TV antenna is going to be highly influenced by its location. The particular best thing to do before you buy any outdoor TV antenna is to do some signal analysis 10 Sharks.
What 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 HD antenna type that is most likely to deliver the best results.
By simply way of example, I actually are in Virginia Beach, Las vegas. It is the most significant city in Virginia and as you might expect, has several TV stations close 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 showed me that there are no less than 48 channels from 23 channels that I should be able receive at my location. For each local TELEVISION 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 of us within 25 miles. Which means that most UHF/VHF antennas should work fine for us.
Not everyone lives in a huge metropolitan area with lots of choices for local TV channels and where just about any digital TV SET antenna will do. If you are in a tiny town in eastern Montana, for instance, you might be able to get four channels from two areas and then only if you use a sizable directional outdoor HDTV antenna installed high on a mast.
Antenna power is deceiving because antennas are passive and don’t actually produce any power. It actually appertains to the antenna’s gain, which measures how much energy of the transmitting antenna’s power your antenna can actually receive. The greater the gain, the better the reception. Gain is also a complex topic so most antenna companies choose to publish the number of the antenna in miles.
It’s not a good comparison tool since range is sensitive to quite a few of local conditions in your way on the path to the transmitting antenna. That said, for the average consumer, it’s probably about the only specification that you will be able to compare.
