ANTOP V/UHF-272 antenna for Bay City, Tx (77414) Opinions?

Spec sheet claims 10dB VHF and 14dB UHF, which seems okay for thirty bucks. Any opinions or experience with this antenna? I'm open to suggestions. Bay City is about ~60Mi from Missouri City where the transmission towers are located. Not too worried about getting the Victoria stations.

Also thinking about a Holland LA-520 In-Line Amplifier 50-2150MHz, 20dB Gain, but I can't find a power supply for it. Is there a favorite amplifier around here for rural TV reception?

I'll be distributing to three end points in the home. None of the cable runs will be more than 100ft.

Thanks.

Kingwood, Texas: To Combine or not to Combine?

http://www.tvfool.com/?option=com_wr...5134e64591db1e

I recently combined a Stellar Labs 60" VHF antenna with my Channel Master 4221 UHF antenna to finally solidify my VHF reception. I'm 40 miles away from the towers in the Houston area and both antennas are mounted in my attic. I receive all channels at over 90% strength.

I have friend that wants to cut the D* cord who wants help installing an antenna for OTA reception. We live in the same general area. My question is if there is a good antenna that will receive both VHF and UHF signals that can be mounted in an attic or do I need to recommend combining two antennas like my set up? Thoughts?

Please post the tvfool report for his location, as the sticky says.
NOTE: Put YOUR LOCATION in the TITLE of ALL antenna threads & TVFOOL info in 1st post


You can do it here:

http://www.tvfool.com/index.php?opti...pper&Itemid=29

Small changes in location can make a big difference in the signals.

The signal strength in an attic is difficult to predict. A metal roof, aluminum thermal barrier, aluminum siding, and stucco wire mesh will block TV signals, as will trees and other buildings. It becomes an exercise in trial and error.

If you can not measure it, you can not improve it.

It would have been helpful if you had at least posted your report. Does it look something like this?
http://www.tvfool.com/?option=com_wr...dfaf8b42e5de49

What channels are most important to him?

Any trees or buildings in the signal path?

He can do it your way or use a combo antenna for VHF and UHF.

Thank you for the report link that I see in you first post. Is that for you or him?

I added the tv report link to the first post. My question isn't about what channels he will receive. I guess I am asking for a recommendation for an attic mounted VHF/UHF antenna that will do the same job as my combined set up.

The report is for my location but we live very close to one another. I don't know his address but it's the same zip code.

IF his attic has similar construction and IF the signals are the same in his area and IF the trees are the same, then this combo antenna will be about as good as your two antenna system:
Winegard HD7694P

and this larger one will have a little more gain:
Winegard HD7698P


Good enough?

Robert:

I started experimenting with antennas when I was 8 years old; I'm now 83. I have been giving antenna advice on four forums for 8 years, and have built many ham and TV antennas. If I have given you bad advice I'm certain the other regulars will shoot me down.

I welcome their input.

I had to drag the information out of you to give you accurate advice in spite of what the sticky stated was required of you.

Your friend still has to try it out in his attic. We don't give a guarantee because every reception location is unique.

The TV Fool report isn't just about what channels you can receive but what it will take to receive them. In your case the HD7694P should be plenty good enough for the job barring any of the issues rabbit73 has mentioned.

I recently put up an HD7698P with preamp for a neighbor who has as miserable a TV Fool report as I do and he receives all the local stations with no unusual issues. Separate antennas are not required.

http://www.tvfool.com/?option=com_wr...b97dd0d97ac6e0

The local stations are the ones between 271 and 273 degrees. Your stations are on the order of 30-50 dB stronger.

How did you combine your two antennas, with a splitter in reverse or a UVSJ?

I used this which I assumed is a UVSJ:

Thank you for answering my question. I wanted to be certain that I gave you an accurate answer about a combo antenna equivalent to your combined separate antennas.

The MCM 33-2230 combiner IS described as a UVSJ, but there have been reports of problems with it. Maybe those users just had a defective unit, or didn't connect it properly. There is a part of the description that bothers me; it is either an error or is a design fault:
Quote:
Insertion loss: 3.5dB
A UVSJ should have an insertion loss of less than 1 dB; usually about 0.5 dB.

I ordered 4 Stellar Labs coax jumpers that were described as equal to gold Monster cable jumpers for 1/4 the price. The quality was so bad, I couldn't even use them because the hex nuts were frozen.

If you suspect trouble with the MCM combiner, I suggest you substitute another brand of UVSJ.

Most UHF/VHF combo antennas have an integrated UVSJ that uses shorting stubs to block any UHF signals from the VHF section, but Winegard uses a combiner and balun in a plastic housing.



The RCA ANT751 uses shorting stubs:



This is the combiner used by Winegard:

Anybody else experience audio drops during Arrow and Frequency on 39 last night? Issue ended for me when 39 switched to its local news.
