FunkyTown It may be the balun or I noticed thereís what looks like a circuit board inside the plastic where the VHF antenna connects to the UHF. Something in there may have gone wrong because itís wired like this:

UHF ó> VHF ó> Amplifier ó> TV

The box is about 2Ē x 2Ē square and there is some circuitry in there. Whatever caused it is still a mystery. There was no dust on the antenna at all. It looks brand new. After 2 years in the attic I figured it would have dust on it. The attic seems to stay very clean. A very strange situation why it would suddenly break with no one going up there in 2 years. Iíd understand it if it was mechanical. Fortunately the cable is 100% fine and so is the amplifier.

Jorgek Good to hear you are back in business.
The only thing that I can think of that would fail on an antenna is the balun. See if you can find a simple basic balun the kind with an F connector at one end and 2 pig tails on the opposite end.
I replaced the PC balun on my CM 4221hd and had a big improvement in VHF Low reception.

FunkyTown UPDATE: The new antenna is in the attic and is working great so something went wrong with the old antenna as suggested by Jorgek. Two nights ago I got a big surprise. I had 4 more channels than I normally have. 18.2, 18.2, 18.3, and 18.4. They were all PBS channels from the US. I have never picked up a US channel at my house before but I think the new antenna is better than my old one. Unfortunately I have lost the stations. It likely has something to do with the atmospheric conditions. I havenít seen those channels since 2 nights ago. Anyway Iím so happy to have my 14 channels back with strong signal. Thank you for everyoneís help.

FunkyTown You are correct. I donít have a chimney. I like the side of the house option. Thanks for that idea.
2019-08-28 09:43 PM
Jorgek My CM 4221HD is chimmey mounted. No holes in the roof.
I suppose your very new house does not have a chimmey?

There are also ways to attach a mast to the the side of the house.

FunkyTown I bought a 25í coax and ran it down into my bedroom wall. I spent the afternoon performing tests a couple of days ago. The screw ends were already on the wire and they are solid. Electricity ran through the wire fine as the red light remained on my amp which was in the attic next to the antenna. The power is injected from my bedroom into the cable. I measured the signal I was getting from Gatineau. My TiVo gave me a pretty high number. The number I was getting from Herberts Corners stations was 30% max. The TiVo shows a black screen when the signal is that poor. I FaceTime called myself and left my iPad propped up on the bed so that I could see the TV screen on my iPhone from the attic. I moved the antenna very slightly to the right and left. Took close to an hour to do this as I only moved it 1 mm at a time. My strongest signal was 30. I unscrewed the antenna and brought it down from the attic along with the amplifier. Hooked it up in my guest room and was able to get stronger signal from Manotick. Maybe it is the wire, but it seems strange it was ok with Gatineau stations. To me it seemed more like some interference. I have a feeling Iím never going to know what happened. When the new antenna comes (hopefully tomorrow) Iíll hook it up first in the guest room to see if Iím getting better signal strength than I am with my current antenna. If I do, then Iíll get the ladder back out and install it in the attic and test it. Iíve been so happy with my attic install for 2 years. Thereís nothing worse than not having reliable station reception. Drives me crazy. It costs time and money trying to fix it too. Iím glad Iím on vacation right now. Itís much easier to tackle this now. Iím thinking about hiring someone to put a roof antenna in. Do you guys have a roof antenna? Iím concerned about holes going into the roof. If it leaks that can turn into a huge expensive nightmare.

Jorgek Its the sudden loss of signal that is puzzling. Do you have a piece of coax that you can temporarly connect to the attic antenna and direct to a TV set down below. Test it. Then add the amp to the temp coax.

I have 1 edge signals that come and go and some that are solid. With the erratic atmospheric conditions this time of season its tough to test ant systems. Conditions change by the hour and also daily.

FunkyTown I wonít contact them but thanks. Itís good to know who to contact. The antenna in the guest room has been working all evening. Iíve lost CTV-2 but the rest are all back now after playing with the positioning. Thereís nothing in my line of sight that would be blocking the signal to the attic. I donít want to leave the antenna in the guest room. Itís in the way and looks ugly. Iíll leave it there for now since I have no visitors at the moment. The antenna is made by Antenna Direct. The model is ClearStream 2V. I threw lots of money out on 6 antennas that supposedly had 80 to 100 mile range but none of them gave me good signal and all of the stations until I bought this one. I even bought the channel master CM4228HD which worked well at my old house but not here in this house. I do have 1EDGE showing on the Herberts Corners antenna stations which makes it a lot more tricky picking up signal, but my current antenna was excellent in the attic until 2 days ago. I was getting 60% strength on some and 80% strength on others. Suddenly after more than 2 years the signal went down to 32% and it would not tune in. I installed it in the attic July 2017 and itís been working 100% since then until now. No one goes in the attic. There is no evidence of critters. The house is new as I moved in June 2019 - newly built. My home was one of the last to be built in this subdivision. Only 4 more were built after mine so thereís nothing recently that went up. The antenna works in the guest room which is 10 feet lower than the location in the attic. Plus now thereís drywall, insulation and vapour barrier and siding to go through and it works better. Itís definitely a puzzle.

Jorgek If you are concerned with possible interference from the contruction site, you will have to contact Industry Canada and not the CRTC.
What model is your antenna?
2019-08-27 09:01 PM
FunkyTown Iím thinking it has something to do with the construction in my area. They are widening the highway and they placed a mobile trailer with some sort of antenna on top of it in a lane close to my home. Nothing changed in my house. Itís all residential here. No big buildings at all. Iím just guessing but Iím wondering if that trailer is transmitting something thatís causing interference. I never thought that would be allowed by the CRTC. Iím just guessing though. I donít know what else. Iím going to buy a new antenna just in case it is the balun. Thanks for that tip.
2019-08-27 06:25 PM
Brightonian If you are sure it is not the preamp And you are very sure your coax and connectors are good.
It could be the balun on the antenna or perhaps something new in your home or surrounding houses that is causing strong interference.
LED lights, communication devices and solar panels to name a few.

FunkyTown That is a possibility Jorgek. Itís working fine now in the guest room but Iíve lost 3 or 4 channels. I have more than I had in the attic though. Why is the question. The attic always gave me a strong signal and all channels. Now my signals are all weak and Iíve lost some but at least itís working better. I never thought Iíd be going down this path again. I spent so much time and money 2 years ago getting this ironed out. Very frustrated. Thank you for the suggestions. It gets me thinking.
2019-08-27 05:24 PM
Jorgek Its possible that the amp has failed.
2019-08-27 04:53 PM
FunkyTown The amp I have is the CM-7777HD. That one has 2 settings. 30 dB and 17 dB. Switching it to the CM-7778 mode of 17 dB gives me less reception. The weird thing is this amp has been working fine for over 2 years in the attic. Two days ago I lost all stations from one transmitter. The other transmitter is coming in fine as per usual. If I remove the amp completely I only get 2 channels. I used to have 12. I was very happy with the setup as holes in the roof worries me but the attic isnít working now for whatever reason.
2019-08-27 04:46 PM
heans your amp is overloading you need to switch it to cm 7778 as it will not overload.
