Something like this for 30. In addition to the foam core board and copper tape youll also need a really cheap balun transformer which you can get at any electronics store two wood screws or solder to attach it and a coaxial cable to connect it to. Heres how to make a TV antenna amplifier.
The DTV signal can travel farther with more power which should provide a consistent picture. The width of this piece will be a bit less than that of the circle but should extend noticeably beyond the projections at either end of the circle.

The indoor unit requires an electrical outlet. Skywalker Signature Series SKY38323 25dB Amplifier VHFUHFFM wvariable gain SKY38323. Twist the straightened wire hanger around your ferrite magnet into a coil.
The thing you have to notice is that if you want to use this antenna amplifier then this thing doesnt provide you with any guarantee that you will receive too many TV channels but it will strengthen the signals of all.

Once youre done with this also draw a pair of semi-circular projections. No fuss no muss. Wideband UHF Amplifier Antenna TV Amplifier Circuit Wideband DTV UHF Antenna TV Amplifier They are pretty simple to build but you may be better off just purchasing one.
Preamplifiers and in line amplifiers. It even has a gain control. Both boost the incoming signal either.
Usually brands use the names ANTInput or VHFUHF. Because it is a non-amplified device it does not require an external power source so its setup consists of placing the antenna panel and plugging it into your TV. Putting it together is easy.
First you should draw a circle on the cardboard using a pen or marker. That might help to prevent signal overload. Different brands may have different terms used for the INPUT port.
An amplifier uses electricity to harness the TV signal and send it on its way with an electrical boost. The end of the cable that is connected to the TV antenna amplifier should be inserted on the INPUT port.

The TV antenna preamplifier consist of two parts. Draw a circle on the piece of cardboard. To make a reflector cut a rectangular shape of cardboard.
Amplification is not guaranteed to fix every instance of poor reception but it is an option. The power its adding to the signal is referred to as amplifier gain which is measured in decibels dB. Use gloves when doing this step as this step can cause.
