Measure the distance from your tv or radio to the nearest wall outlet.

Tv antenna circuit. The circuit shown here is of a tv antenna booster based on the transistor bf180. Wanted to give our over the air tv antennas a little boost. It should be 1x3 inches 2 54x7 62 cm or 2x3 inches 5 08x7 62 cm. Just plug livewave antenna and it instantly gives you access to tv channels broadcasted over the air for free.

Prepare a wooden board. Each section should be 14 inches 35 56 cm long. The first stage is an band pass filter constructed by the c1 cv1 l1 l4 c7 and c3 the second stage is a base common. The circuit operates in the uhf band and has a gain of 15db.

It is formed based on bf180 uhf transistor. Digiwave ant2084 digital tv antenna. 15db uhf tv antenna booster this is an uhf band tv antenna preamplifier circuit with 15db gain to build easily. Capacitors c2 c3 c4 c5 and inductors l3 l4 forms a uhf band pass filter.

A coaxial cable transmits radio frequencies into a tv or radio antenna port. Each should be bent so that each side is 7 inches 17 78. Small imperfections in antenna tuning will cause a potential difference to exist in the final amplification circuitry heating the final part of the transmission circuit. L1 l2 5turns 0 8mm ø 5mm ø the second turn from ground.

Antenna with strong performance across channels 2 69 best for uhf spectrum 21 69 great within 70 miles or more from transmitters. Cut 8 sections of copper wire. Over the air tv antenna amp. Large imbalances can feed high potential differences back into the transmitter circuitry causing dielectric breakdown and arcing.

Ihave already done several instructables about antennas though it would be nice to something a little different. Came across this circuit to see if it would work. A very simple and cheap tv antenna amplifier circuit built with bf961 a n channel dual gate mos common transistor used for input and mixer stages especially for fm and vhf tv tuners up to 300 mhz. The input signal is fed to the emitter of q1 through this filter.

Bend each section of wire. Using your home wiring as an antenna requires plugging a coaxial cable into a wall outlet using an adapter. It is designed after advanced military cover technology. Livewave antenna is a completely modern plug in antenna which converts the standard cables and wires in your home into a super antenna for a wider signal range.
