Default How high should the antenna be?

We are getting ready to put up an outdoor antenna but we aren't sure how high the antenna needs to be. We bought a Channel Master 3020 antenna. We are in a fairly rural area in Northeast Okla. with no tall buildings near us, only a few trees. Here are results that I got from antennaweb.org in our zip code of 74354

yellow uhf KODE-DT 43.1 ABC JOPLIN, MO 57 22.7 43
yellow uhf KOZJ-DT 26.1 PBS SPRINGFIELD, MO 57 22.7 25
yellow uhf KSNF 16 NBC JOPLIN, MO 56 21.9 16
red uhf KSNF-DT 46.1 NBC JOPLIN, MO 56 21.9 46
violet vhf KOAM-DT 7.1 CBS PITTSBURG, KS 23 23.6 13

There are also Tulsa, Ok stations that we would like to be able to receive. Tulsa is about 90 mi. to our southwest. Your help is appreciated.

Generally, the higher the antenna is, the better. It won't have to be very high at all to receive Springfield/Joplin area stations, as you are close enough to have line-of-sight for those. If you really want Tulsa stations at 90 miles, you'll probably need to get the antenna as high as you can. If there's some hilly terrain between you and Tulsa, you'll definitely want it high.

The only time I've found that a high antenna can be a bad thing is when there are a lot of stations within reach, some sharing the same frequency. One of my digital local Milwaukee stations is broadcast on channel 28. Sometimes, when analog channel 28 out of South Bend, IN comes in strong, it can interfere with the local signal. For you being in a rural area though, you probably won't have to worry too much about co-channel interference.

What Creed said. If you look around your area you'll probably get a good idea of what the baseline minimum height above ground level is. In my area its about 35ft, so I put my antenna at 45ft. I drove through a rural area one time and there were five houses next to one another all with 80ft towers in their back yards. I thought to myself they'd have been better off pooling their resources for one big tower with several antennas and splitting the feed.

The 3020 is suited to the stations listed in the OP. To pull in Tulsa, please read "Tigerbangs' prescription for deep fringe reception." You'll need everything he recommends at the top of that thread. According to what TVFool shows for the ZIP code, this will be worth it only if you want to receive MyNetwork, Tulsa's independent stations or OK-based newscasts. Otherwise, you'll just be getting the same networks available to you now.

I'm over here in Parsons with an attic setup. I have a VHF antenna and a cm 4228 with the 7777 as the preamp. I'm able to pull in the 7.1,7.2 FOX, CBS and the PBS station. I cant pull in ABC or NBC they are not at full power so I hear. It looks like your closer to the towers than me. Some mornings I'm able to pull in some Springfield digital stations. GOOD LUCK !
