Indoor TV antennas are hit and miss
 

Is there any indoor TV antenna that would work for my home that is approximately 40 miles from the TV stations. If not what outdoor tv antenna would work. My daughter is in college and this is a rental house and she can't afford cable.
Thanks.
Steve

Greetings Steve,

Indoor TV antennas are hit and miss. To date I have not had one person say that their indoor antenna works flawless. Usually there's a channel or two that don't come in or the signals break up on certain channels or the antenna needs repositioned when changing channels. The things to be considered are the construction of the house. Aluminum siding, foil faced insulation and brick are all signal blockers. Also the elevation where the house is located will have an effect. Is it in a valley, on a hill etc... Is the house surrounded by other buildings or is it open in the direction of the stations.

To be truthful a good pair of TV antenna rabbits ears work indoors as well as the fancy looking higher priced indoor antennas. If the I suggest the Winegard SS 3000 SharpShooter TV antenna. I'm reluctant to call any antenna an HDTV antenna but this antenna does have circuitry designed specifically for digital reception.

Your best bet for good reception and the simplest outdoor solution would be the EZ HD antenna. With some elevation this antenna will easily provide good reception on channels forty plus miles away.

I would check with the landlord before I spent time and money on a TV antenna installation on a rental house. If you install a pipe along side of the house or work some kind of agreement, you may be able to take it with you when she moves out.

If I can assist you further please don't hesitate to contact me.
Best Regards,
Denny


Multiple antennas, one downlead

I live in North Manchester, IN (46962).  I had 2 Channel Master 3021 antennas pointed at 80 and 190 degrees with 300 ohm down-lead. I added a third 3021 over the weekend pointed at 320 degrees with a pre-amp and RG6 The picture on all channels is worse for the most part.  When I unplug the the tv antenna pre-amplifier power supply the picture is even worse, so the pre-amp is working.  I can't find any information about running multiple antennas on the same down-lead. Do you have any suggestions? Joel

Joel,
Each time an TV antenna is added to the system the effectiveness of each antenna is reduced. One antenna will provide better reception in the direction it is pointed than it will when a second TV antenna is added pointed in a different direction A third antenna will reduce each antennas range even more. To determine if this is the problem try hooking up each TV antenna separately to the pre-amp If they perform well separately then the problem lies in the addition of the third antenna.

How did you join the antennas to one downlead?

There are some possibilities to explore let me know the results of your test and we'll go from their.

Good Luck and be safe,

Denny

Denny, I hooked up the new television antenna to a balun and then to the tv.  It was watchable, and with the other antennas all plugged into the tv antenna amplifier, the pre-amp should compensate for the less effective antennas. I haven't tried plugging each antennas into the pre-amp separately like you suggested, but I should have time tomorrow.  I have the 3 antennas plugged into the pre-amp with 300 ohm twin lead, and then RG6 from the pre-amp to the power supply and tv. I have the antennas vertically stacked.  Would there be improved performance if they were all at the same elevation?  A good way to get 3 antennas on one down-lead may be the hardest thing to figure out.Thanks a lot for you help, and I'll let you know the results most likely tomorrow.

This site has some good information called merging feedlines. I have communicated with the site owner on several occasions he knows what he's talking about.

Denny

Denny, Thanks I'll drop him an e-mail. I had actually run across that site yesterday after I wrote you.  From a design standpoint it looks like I'm out of luck. I'm just looking for a practical solution to hook them up in the best way possible.  Evidently multiple TV antenna systems aren't common.  Where I live that's all people have, so either no-one has good reception, or someone has figured out a good trick.  We're in the middle of 3 transmitting locations, and where I live it's almost a perfect 120 degrees between each of them which is kind of interesting.  Thanks a lot for your help, and I'll let you know if I dig up anything.

Joel,

Joel, We are in the same situation here at our location. We have Flint east about 55 miles, Lansing south about 50 miles, Grand Rapids Southwest about 70 miles and Cadillac/Traverse city Northwest about 80 miles. Without exaggeration nearly every O.T.A. antenna within 30 miles of our location is a Winegard MS 2000 omnidirectional TV antenna.
Denny

Denny, I tried plugging in each antennas one at a time, and I got the reception I expected.  I've been talking with Ken at hdtvprimer.com, and we've come up with a couple things to try.  I'll let you know how it works out.

Sounds great! Denny,

Denny, I finally got a good compromise by trying different combinations of antenna direction and different ways to connect twin lead.  It's not perfect, and I couldn't recommend it to anyone else simple because of the time I spent on it.  I learned a lot, and I found some interesting things, like the lowest of the 3 antennas I have pointed towards Indy, the farthest stations. I found flat wire still performed the best, and I never did try a combiner because I didn't want the signal loss, and I'm pretty well burnt out on the project. I did try a 4th TV antenna to see if I could get it to match better, but it didn't help much.  Supposedly reflections will only be canceled if the antennas are in the same RF field, and if they are pointed in different directions they'll be in different fields, and that's what I found. If I ever have to use multiple antennas, I'll try a combiner first because it provided antenna separation, and hope there isn't too much signal loss.
Joel

Joel,

Thanks for letting me know your results. I'm glad you found a compromise to the situation. Working with multiple TV antennas in different direction can be a real pain in the butt. I guess that's why they invented the TV antenna rotor. What works at one location with particular antennas doesn't necessarily work at another.

Tripod TV antenna mount

Hi Denny,

I would like to use a tripod for my tv antenna mount but I'm a little skeptical about putting anything on my roof. Do you have any advice, what's your experience?

I understand your concern. Tripod TV antenna mounts have received a bad reputation because of improper installation procedures. I have installed hundreds of tripods for my customer's and to date have not had a single negitive reports. See installing a TV antenna tripod. Have you considered an eave mount?
