Waldo Kitty Asks About Omnidirectional Antennas

i’m trying to figure out some of the abbreviations you used on your http://www.highdefinitionblog.com/?page_id=24 URL… HOA being one of them…

i’m considering the possibility of making a vertical omni-directional antenna to pick up the HD signals available in my area… we have had, for many years, a directional antenna with a signal amplifier… in recent discussions, thoughts, and conversations, the first thing that came to my mind was to simply mount an omni-antenna made from RG6 and connected to the amplifier… this way, we don’t need to worry about rotating the antenna that feeds the six in-house televisions and we also don’t need to worry about getting a HDTV “convertor” for each set… to be honest, we are currently using 3 sets as “base units” and then using some (radio shack) transmitters to put those signals out to the other TVs in the house… no more than three sets are in use at any one time and none of the “dupes” are in use at the same time… if they are, that’s because someone doesn’t want to watch in the same room as another…

sure, we have directTV but, contrary to the /lies/ they (the satellite companies) tell, satellite signals DO get blocked by clouds and heavy rainfall… during those times, we may switch to OTA signals… our interest is in being able to pull as many OTA signals as possible without hampering others watching their shows from the same antenna… thus, my idea of an omni-directional antenna connected to the existing amplifier…

can you help?

thanks for your time and attention…

HOA means Home Owners Association.

There is a reason why antennas are directional. It is to reduce the amplitude of signals that are reflected from objects from the side or rear of the antenna. Without doing that a fairly strong signal can arrive at the antenna slightly later than the primary signal and effectively scramble the primary signal. That is why most antennas for TV use are directional. The omni-directional antennas generally only work within a few (less than 5) miles of the transmitters. If omni-directional antennas would work for general use, there would be no need for directional antennas.

I understand the issue of multiple rooms and such and in some instances that issue can be solved with multiple antennas, each tuned to a particular station. This can require the use of special combiners tuned for a single channel insertion and multiple preamps to make up for the losses of the combiners. This can be a pretty complicated and should involve someone that has done this before.

Otherwise, you can just give an omni a try and see what happens.

Sorry I don’t have a magic bullet for you.
