View Full Version : Can't get analog signals

I recently made a Gray Hoverman single bay antenna. It allowed me to get real channel 44 beautifully. I am not able to get 49 or 41 which I believe are analog signals. I thought maybe it was because my TV converter box (I have an old style TV) was not pass through so I bypassed the TV converter box. Still no signal on either of these channels, that is, the tv screen is nothing but noise, not even a blip of a signal. From the transmitter report, it looks like I should get both of these if I am able to get 44. Any ideas? Thanks.

Channel 44 is a digital channel--http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3dec1271df4e0056%26t%3dALLTV%26n%3d4
Channel 5 is an analog channel , but the ERP is just about 1 watt of power. I believe the the grey-hoverman antenna is a UHF antenna and channel 5 is a VHF antenna.
On your TV fool report just click on the "call sign" for info on that channel

What about ch 49 and 41? Does it look like I should be able to get them?

RF 49 seems to be a digital channel and you should be able to get it, since it has good NM value.
RF 41 has NM of -25dB. Unlikely you'll get this.

Per rabbitears.info (http://www.rabbitears.info/market.php?request=station_search&callsign=WDON#station), WDON is 'off the air' at this time.
rabbitears.info also reports WJJN as 'off the air'.

Thanks for the rapid replies. I was wondering if they weren't broadcasting.
One more question. What would it take to get VHF Channels 7 WJHG or 12 WSFA. Thanks.

I would go with a 10 element high-VHF Yagi such as the Winegard YA-1713 or Antennacraft Y-10713. You'll need a rotator or two of those antennas and a Channel Master CM 0577 Join-Tenna (http://www.channelmasterstore.com/Channel_7_Join_Tenna_Antenna_Combiner_CM0577_p/cm-0577.htm). To combine with your UHF signals you would need a UVSJ.
If you're adventuresome and handy at DIY antenna building you could build a high-VHF or two. http://forum.tvfool.com/showthread.php?t=1106

What is a UVSJ? Where would I get one? Thanks.

My bad :o
A UHF VHF Signal Combiner (UVSJ) is used to combine UHF antenna output with VHF antenna output into a single feed line, usually coax.
