picture is a made 50 ohm dipole with a ground plane made for microwave frequencies. the only difference in tv is length of the main antenna. then there is the coax velocity factor.
hello everyone, this post is all about 75 ohm antennas if you dont know what a real 75 ohm antenna is please dont make a comment. no transformers are used.
new post because of off topic tech. first, there is no such thing as a hd antenna. regardless what people tell you 300 ohm twin lead is not dead at all they are miss informed. coax is better for electrical noisy environments (shielded wire) only. twin lead wire is better than coax if electrical...
i did a post here back in the day on multiple antennas you will need a combiner or use ultra low loss 300 ohm wire connected correctly then run the coax. as for vhf uhf sometimes i skip the vhf if there is not enough stations to justify a combo antenna purchase and get a bigger than needed uhf...
hello everyone, been long time since posted. i have noticed air tv programing is starting to look like basic cable/sat same type subject grouped to a channel. is there a list of current subject based off-air networks. if this keeps up even people that must have basic cable /sat programing will...
hello, just wanted to let everyone know the u4000 uhf 60 miler antenna that radio shack sells works very well in heavy tree locations. port orange, fl to antenna farm in bithlo, fl about 45 miles , trees in way. ! works.
The TV fool looks good do you have any nearby trees or buildings? What is your building made of concrete or wood? The more terrestrial info would help to better describe where you are currently trying to use those antennas to get a TV signal.
I would check each coax F connector end if still good. From my past experience with TV installers work some like to use twist on connectors not good for stopping water. I use crimped lug F connector ends the ground holds up better than the twisty ones. If you have crimped lug F connector ends...
Hello rodder, The time for all DirecTV receivers is set by a satellite. When using the receiver for OTA only the time dosnt work and now the program guide dosnt work anymore when connected to the 18 inch dish.
hello durandtheman, if you really want to try a directional antenna and you have a balcony just put up a di-pole tap at the center of the guard rail everything must be properly di-electric.
need any antenna
Hello, There is a not well known antenna that could be tried they are called an "absorption antenna" they only work in the UHF band mostly used commercially in cellular phones or wireless networks. You should be able to be on the back side of an apartment building using a new...
I installed a cheap folded dipole antenna in an attic using ultra low loss 300ohm wire. Everyone should try this too like the home made bow-tie antennas. The installation was 8 feet across and 3 feet down the center (frequency band overkill) to a 300ohm-75ohm transformer glued then taped to the...
