Re: [DIY] TV HD antenna?

I will be very curious to know- as I am looking into this also.

When we get this thing up, I will relate how we decided to do it and send pictures.

My husband found the drill rod and will weld rings on it for the guy wires.

Go to www.antennaeweb.org. you can put in your location and it will let you know where the stations
are in relation to you. Keep in mind that not all of the stations broadcast on the UHF frequencies. I l
Live in Philadelphia, and I put up one of those HD antennaes and I got about 30 stations, I replaced it
with an old style UHF/VHF antennae and now I get 50 stations. The thing to remember is that when it
comes to antennaes, most of the HDTV stuff is hype. The only thing you have to concern yourself with is
wheter the Antennae you put up will receive the frequency that you need.

The bigger the anenna (or longer the rated range) the higher the signal strenght. I would go with a bigger
antennae and no amplifier. I makes for a much simpler set up. Where i live you can put up a hunk of metal
and receive quite a few stations and I put up an antenna rated for 100miles. The other thing to consider is
that you need to ground your installation. If at all possible you should run a grounding rod and grouns the
structure and the antenna. There are a couple of reasons for doing this, the main reason if the set up ever
gets hit by lighting you give it someplace to go. Number two, it will improve your Signal to noise ratio and
give you better results. I have been a Ham Radio operator for some 20 years and a decent antenna installed
well will make the rst of the set-up sing.

My antenna knowledge is ancient theoretical stuff, from studying 
  electronics. Here are some rules of thumb that applied a cpl-3-4 
  decades ago. TV was VHF, before UHF came along. Maximum 
  range was ~60 miles, if there were no big hills in between.
  
  Teachers blacklisted for supporting withdrawl from Nam, married 
  teachers of like minds. Both w/o work, they moved. Affordable was 
  > 70 mi from town. W/o TV, even kids were bored, after the city life.
  "Mom, I'm bored." "Well dear, you can milk the goats or read a book."
  In 2 years, 3 of 4 were geniuses. True story.
  
  Hubby is right. Better antenna is better. Less snow, esp when 
  conditions are unfavorable... which is when you will be knitting, and 
  watching TV. UHF doesn't go as far as VHF, which WAS the lower 14 
  channels. New digital transmission is sorta like, 
  VHF > UHF > Digital UHF > Digital UHF HiDef.
  You will want "the best" if you are very far out.
  
  Amplifiers also need to say ~2GHz for HDTV. Some will say 1GHZ 
  and claim to be HiDef. It can sorta be true, but also not work under 
  non-ideal circumstances. (If HiDef is an issue. Not v likely on 
  transmitted TV, but I dunno... You'd have to call the individual tv 
  stations. Unless you can google this with Avanced Search.)
  
  There might be a ~Transmitted TV for Dummies book, out there, 
  even.

  >Is there anyone out there that has some knowledge about TV  antennas?  We would need a *UHF Violet * for it to work from our country  position. This had a figured milage of 33 miles, at 268º  position.  My husband insists that it would make sense to buy one that is  good  for over a 100 miles to ensure good reception. I'm clueless.  Anyone familiar with the validity of those thoughts?  carmen
