Need help getting in channel 13
I live in a hilly area near Greenville, SC and am located about half way down a hill with the hilltop being to the north. I am also surrounded by trees. I have a hd8200u mounted on the roof roughly 25' above ground with a rotor. I am not able to get a decent signal from channel 13 located in Ashville, however, I get channel 31 just fine along with about 38 other channels. I am wondering if there is something I can do with my current setup to get channel 13 reception or do I need to try a different antenna? Here is my location... http://www.tvfool.com/?option=com_wr...60edcee7171cb0
Thanks for your help, Russ |
Hi Russ,
The tv fool database has been missing major and minor stations recently. Hard to tell if there are other ABC stations you might try. You mention you get channel 31. W31DY looks like a translator for WLOS TV13. If that is correct and assuming the tv fool report is accurate, you are in a weak signal area for WLOS's main transmitter signal. That is why there is a translator nearby. The tv fool report indicates a 2 edge signal at your location. That means the main signal is reflected away from you twice or more. With the trees and hill, it is no surprise you are having trouble with WLOS. I doubt any other antenna will do as well or better. You could try some kind of amplification but if you are receiving ABC via the Rf31 translator why go thru the expense and bother???? |
Well, actually I meant channel 33 WUNF-TV, which main tower is in the same location. Not sure if there is a repeater that is closer for 33.
|
You may want to call or email WLOS and talk to one of their
engineers. They can tell you if they have any translators near enough to you for consistent reception. As I previously mentioned, the database for tv fool has recently become problematic with missing and erroneous information. |
OK, thanks Joe

I called WLOS. They have a translator in Simpsonville. The engineer says it's a flip of the coin whether you get a better signal from Pisgah or Simpsonville. I'll give it a try and see what happens.

Hello, Russ
The channel list for your location from RabbitEars.info is probably more accurate: http://forum.tvfool.com/attachment.p...0&d=1512785297 The FCC DTV maps site doesn't list translators http://forum.tvfool.com/attachment.p...2&d=1512788862 What network are you looking for, ABC? W31DY in Pickens has it if you can't get WLOS: http://www.rabbitears.info/market.ph...callsign=w31dy It's a wonder you get anything with your antenna at 20 feet in all those trees: http://forum.tvfool.com/attachment.p...1&d=1512785749 You have some strong local FM transmitters that might be causing interference to WLOS on real channel 13: http://www.fmfool.com/modeling/tmp/3...6/Radar-FM.png An FM filter might help: https://www.antennasdirect.com/store...on_filter.html |
Thanks for the info. I prefer WLOS for local programs. It's funny that I can get nearly everything on that list but 13 WLOS. I get 33.1 very clear. As far as FM interference, thats a very good possibility but why just 13? Does Hi-V band with my particular antenna have anything to do with it? I am pointed right at 324 degrees and get all the other stations in but 13.

They can cause interference from fundamental overload or from a second harmonic of an FM transmitter. The second harmonic of WYRD-FM on 106.3 MHz is 212.6 MHz. Channel 13 is 210 to 216 MHz, but WYRD-FM is not one of your strongest FM channels, so the interference would more likely be from fundamental overload from the stronger FM transmitters. WLOS, on real channel 13, is your weakest VHF-High channel. To test the theory, insert an FM filter/trap. Another possible source of interference to WLOS is electrical interference, which is worse on VHF than UHF. It can be caused by LED and CFL lamps, switchmode power adapters, electrical motors, & etc. You can listen for noise on a clear frequency on an AM broadcast band portable radio. |
Again, thanks for the info. I was just about to ask if anybody new what the frequency is for channel 13. I will order the FM filter and give it a try. My antenna wire runs directly from the antenna to the tv tuner. Where would be the best place to place the filter?

Near the TV would be convenient.
antenna > long coax > grounding block > coax > FM filter > short coax > TV If the antenna is outside, the coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge which will tend to discourage a strike, but the system will not survive a direct strike. http://forum.tvfool.com/attachment.p...9&d=1441917363 |
Good News!!!
While waiting on the FM trap, I started experimenting with the antenna pointing direction, (winegard 8200). I normally got my best signal for 13 while pointing the antenna just west of 324 degrees, something like 318. Last night, I decided to leave the tuner set to 13 and do a complete sweep counter clockwise while watching the signal meter on the tuner. I was getting absolutely no signal strength until just before reaching full north. All of a sudden I got a huge spike. I got the best signal strength right at 4 degrees. I don't remember having done that before for 13 and I never would have expected any decent results being pointed at least 40 degrees north of the target. But I must say I am impressed and thrilled. I checked it out again in the middle of the day just to make sure it wasn't a fluke and I'm still getting great reception. I'm pulling in channel 17 as well. I don't understand why it's working so well at 4 degrees north but what can I say, it works!!! |
Signals don't always travel in straight lines. They can bounce off of and get twisted around from buildings, hills, trees roof tops, etc. Both from the vertical and horizontal directions.
I get my best reception about 30 degrees off the straight as arrow aiming, and pointing up a few degrees from level. |

Some antennas have brackets that allow for slight upward tilt. Try doing it manually first. If it makes a big improvement, you could custom fabricate something.
