Can a Satellite Dish Be Used as a Tv Antenna

Well kinda, simply don't expect it to work very well. The first thing you need to know is that a satellite dish is an antenna, simply it'due south designed to choice up signals in a completely different band from a TV antenna. You won't get a lot of point just past trying to connect the dish to the TV's antenna in port. In fact it would surprise me if you got annihilation at all, unless you were very close to the towers. The receiving area is very pocket-size, and while the overall design of the dish would help, the larger waves of broadcast Tv set just wouldn't be well received by the dish'southward LNB.

Let's take it further.

But let'south say that you bought just the reflector and arm associates and then attached a small antenna similar the HD-BLADE to information technology. In a case like that I would expect to become some signal, but not very much. The reflector of the dish focuses all the indicate into a very small expanse, so most of the antenna would be unused. If yous got whatsoever bespeak it would be just from the antenna pointing the right direction. Of course there would too be the short term problem of keeping the antenna in the right position. These flat antennas tend to be fairly floppy when they aren't mounted to a wall. Mounting to a piece of plywood before you lot put it in front of the reflector would aid. Of course it wouldn't look very skillful.

What about those dish-style TV antennas?

I've seen dish-mode antennas for Tv reception and they work, but connecting a satellite dish to an antenna is just going to disappoint you. The thought is sound but it simply doesn't piece of work. It's possible that if someone spent enough money engineering the thing, it could perchance work, simply the resulting antenna would probably merely exist too small-scale and wouldn't necessarily work ameliorate than a pocket-size outdoor antenna like the Xtreme Signal HDB2X.

In fact, the HDB2X is engineered very much like a dish, although information technology doesn't look like it. The horizontal bars in back act as reflectors, just the style the big "dishy" reflector does on a satellite dish. The reflector assembly on an antenna is large and flat because the broadcast waves are so much bigger. This would require a gigantic "dishy" reflector to aim everything properly, if you were going to go that way.

The horizontal confined on the HDB2X accomplish the aforementioned function as the reflector on the dish (the "dishy" role) as they focus signal onto the antenna elements, which are the 10-shaped parts on the front. This is a much more economical way of dealing with the same problem and works very well for antenna signals. Of course, something like that isn't going to do well for satellite signals, which is why satellite dishes are shaped the style they are.

Utilize antennas the fashion they were meant to be used

There's a lot of physics involved in explaining why unlike antennas are better for different signals. Most of it boils down to this. Imagine an antenna is like a net, communicable dissimilar signals. Some signals are physically larger than others. (This is really true) Therefore, y'all need a dissimilar size net to take hold of them while nonetheless letting other signals that you don't desire pass through, and using as petty material every bit possible so as to save coin. In that location's a lot (a LOT!) more to it than that but that's a adept way to remember about it.

It's good to exist thrifty, only…

Using a satellite dish as a TV antenna isn't going to piece of work very well no matter how you lot do it. It's never going to return the level of signal you want no matter how much time yous invest. You're much better off simply shopping for an antenna at Solid Signal.
