the problem with tv signals are the reflections bouncing all over the place.
This is why a dipole doesnt work too well, because they recieve equally well all the scattered signals, which gives the snow and ghosting, the signals are out of phase. What you need is a beam antenna, the typical tv antenna with many elements shaped like an arrowhead. This selects the strongest signal from only one direction, eliminating (hopefully), the snow and ghosting. A signal amplifier mounted directly at the antenna will also help with the losses of a long twinlead run. The antennas are typically designed with a 300 ohm impedance, jthus 300 ohm twinlead is the match. If your tv reciever or vcr or whatever you have in the house has a direct connection for twinlead, then just hook up to the two screws. If it is designed for a coax cable, you will need the little gismo that has the two screws on one end and a cable connect on the other. This little guy is theadaptor that is the impedance transformer from twinlead to 75ohm cable. Good luck your results may vary. Don't look at the laserbeam with your remaining eye. |
