Default WBRE Wilkes-Barre OTA Problem

I can not get WBRE 28.1 (CH 11) to tune into my DISH 622! I have a home-brew antenna and get GOOD signal on every other station in my area! I get WNEP, WOLF, CW, PBS (UHF's), and yes WYOU (CH 13 and also VHF as is WBRE)! All channels are in the same direction from my home. All antenna towers are on the same mountain, 22 miles away. In fact, I think that WBRE and WYOU antennas are on the SAME tower! Why would I not be able to get this 1 station????? Dish receiver reports all signals are 78% plus! Just can't get WBRE for some reason!

Antenna is the 'coat hanger' home brew from the internet (4 rows of dual V's, with a reflector, a transformer and 75 ohm into the receiver). It's up about 24FT. I live in 18603.

I'm thinking it must be the receiver is screwing up somehow! I even attempted to 'manually' enter the channel (11) into the dish receiver and it shows no signal.

Any suggestions would be appreciated. Thanks!

What's screwed up is expecting a UHF coat hanger antenna to pick up a VHF signal.

Use a VHF antenna for predictable and reliable results!

The U-tube DIY 4-bay has poor high VHF reception. Build a DIY M4, they have useful positive gain on both UHF and VHF. See: http://m4antenna.eastmasonvilleweather.com/index.html

Like I said, however, is that I DO get WYOU (which is also VHF and at the same transmitting location as WBRE)!!!! I get 82% signal on WYOU!!! 0% for WBRE????

I understand what you are trying to say about my 'rinky-dink' antenna, but why would one station come in fine, and the other with nothing when both are on the same band and at the same location!????

Thanks....

After looking at the link in your post, this is EXACTLY what I built! I added a screen reflector to the rear (about 1")!!!!

Which M4 did you build (ie whisker length and bay spacing)? The reflector is 1" behind the elements? If so, it should be about 4 inches behind the elements. Locating the reflector 15 inches behind the elements tends to optimize vhf reception.

Can you post your exact address tvfool report? Using the generic zip code tvfool (http://www.tvfool.com/?option=com_wr...9900128ec9759b), all of your locals are two edge which means they must refract over two geographic features prior to getting to your location. Tvfool is only a projection and can be too high, too low or about right. Given that the towers are two edge, you may be able to improve reception by playing with antenna location and mount height. Find the spot where WBRE and the other stations come in....

Multipath is always a possibility with two edge signals. Using a more directional antenna and finding ideal mount heights/location are important for multipath. Unfortunately, VHF antennas have quite wide beams and there is not a more directional antenna available for real channel 11.

The one I built closest matches the 4 bay, 9 1/2" Whisker, 9" Spacing. I was not aware about the reflector distance, this weekend I'll try to increase that to at least 4".

This forum won't let me post a url since I have <5 posts. Here is MY info from behind the URL you sent me, just add the front part and you should be able to see the report.

/?option=com_wrapper&Itemid=29&q=id%3d99009ca150199 0

Here are the stations from that report that I get just fine! WNEP, WYOU, WVIA, WOLF, WSWB, WQPX

Looking at that data, again the difference between WYOU (I get) and WBRE (I don't) is nearly identical for the power output, location is the same, and it shows LOS for both stations.

Thanks for the help.

Here is your tvfool report: http://www.tvfool.com/?option=com_wr...99009ca1501990

The 9-1/2 x 9 M4 is the correct build for your location. Good job! :-)

How wide is your reflector? A 24" reflector is wide enough for UHF signals but significantly attenuates VHF signals. Your reflector should be 32 to 36 inches wide. With that said, I have a VHF channel 8 that is receivable with bare coax on the roof. The tvfool noise margin for this station is 56 dB so the antenna mods will help some but do not explain why the station is not receivable. My M4 picks up channel 8 laying flat on the ground...

Can you try different mount locations? There maybe some obstruction that is blocking WBRE at your location and changing mount sites/antenna heights may provide a hotspot for you.

I do have a local obstruction to my attic mounted antenna. It doesn't completely block stations but significantly attenuates when the antenna is located in specific parts of the attic. My final install was a location that eliminated the block...

Good luck!

Thanks for all the help! I'm going to try tweeking this weekend. Up/down, left/right. Also going to move the reflector back 3-4 inches. I'll let you know if I can finally get WBRE!

Thanks again.

My brother, who works for Siemens, and had worked for ABB and Arriva, once had a boss who said, " Never deal with a person who carries his money in a snapper purse!

Bottom line is - they are not just worried about how much something costs, they are also worried about loosing their coinage...

You can't sell something to someone who thinks that they do not need anything.

With all the old VHF antenna's in the garbage, and this person refused to repurpose one to pick up some stations 20 miles away, because he thought that because they were so close - he didn't need it.!

Reception does not care about finances, or age, or where you live, all it cares about is that you put something up in the air as high as possible and use the coax with the least amount of loss, and use a antenna with the most amount of gain.

I sold a XG 91 to my mom, and they put it up 40' above ground, and the local PBS station - 820 KW is only 27 air miles away, and on channel 15 / yet they could not receive it.

In their opinion / if you can't receive it, it must not exist anymore.

So I hacksawed a old Channel Master UHF / VHF antenna in half and hooked it to the CM 7777, after opening it up and checking the trap.
They then were able to get 3 more channels, not 3.1 / 3.2 / 3.3

But 3 / 8 / 19 - and all that was associated with them...

They didn't want to spend any more money, and they didn't want some ugly antenna, but when it worked - they didn't take it down.

Hope what ever you do, it works for you.
