I use a medium gain preamp as I'm not that far away from the towers. Very few people need high gain preamps unless they are Fringe. Your issue with your Tablo is user error. You can very well overload any TV's Tuner easily with a high gain preamp, let alone a Tablo.My highest gain preamp pushed my tablo into overload.Had to cut signal 6db.
I don't know why but I find I get better results with the CM-7778HD preamp (on low gain) and the CM-3414 distro amp, but then I'm running the OTA feed to 4 TV's and the length of coax from the distro amp is ~100'. I'm across the lake from Toronto. LOS to the CN Tower to get the channels from Buffalo, I have the Escarpment to deal with.Don't use a distribution am in concert with a preamp near the antenna.
Either keep the Preamp / Splitter going, or use only the distro amp. Not both.
I too am having trouble with receiving 2,4, 7 and their subchannels but it happens every year. I pretty much figure that if I am picking up 29,17 or any buffalo channels it is not my equipment and more the conditions in the atmosphere, Just for context I am about 20 minutes west of Pearson and I get 5, 9, 11, 14, 17,19, 25,29, 31,35,40,41,47,49 and 57 right now. 2,4,7,23, and 51 along with their subs have gone dead to me and not receivable but they will be back soon...I get this every year.Well after many months..I am still having issues with signal drop outs and disappearing channels, I have tried everything...I thinks maybe I had too strong amplification...so I removed the pre-amp altogether and now am using a cm-3414 distribution amp and things seem a bit more stable..I am still running the 4max antenna....I think maybe I will try stepping down to the 2max...channels 2.1-2.5, 4.1, and 7.1-7.4 are still a problem...maybe the 4max still too strong?..any recommendations?
Just like that all of those channels that I was having trouble receiving came back yesterday. Weird as it was in the middle of a snowstorm but it was definitely nothing I did to adjust my equipment. Sometimes the atmosphere or solar radiation or something like that is just not conducive to receiving those particular stations.I too am having trouble with receiving 2,4, 7 and their subchannels but it happens every year.

I think they would have to apply to the CRTC to rebroadcast the American stations. I would like to know why they don't add subs of their own channels for example CTV could broadcast some TSN although I do understand the obvious cable subscription conflicts. Why though does the CBC not sub their news channel on their signal? We are paying for it with tax dollars after all and they could also include 24-hour streaming of GEM or something? I think in the end we have to realize that the CRTC is not necessarily consumer friendly.Does anyone know why Rogers or Bell doesn't pick up any of the sub channels? It doesn't cost them anything and it would be good to have some of these extra channels especially if the rumors are true the ION may be changing to a regional sports network owned by Scripps.
I can see how it might not be possible to have one crown corporation fight another with regards to the CBC but I am pretty sure that the CRTC could make licensing approvals based on broadcasting subs with regular station content, especially news channels, part of the deal. I am not saying it is their fault....just that they are not helping or quite frankly interested in helping. If that big dog has no teeth where is the security? Let's just let all Canadian broadcasting fend for itself online.The CBC is already planning to shut down all their transmitters. That's after abandoning its promise to serve 90% of Canadians with OTA and already shutting down most of them about 12 years ago. CTV has already applied to be exempted from simsub station requirements so it can shut down its transmitters. The writing is on the wall, Canadian OTA is going away as soon as soon it is financially viable so why would they expand or upgrade service by using subchannels? The CRTC opposed the CBC decision but has no power to stop it. The CRTC refused CTV's application, keeping most CTV transmitters operational. Subchannels are allowed by the CRTC but no broadcasters have applied to add them. So why is lack of subchannels the CRTC's fault?
