I got a CM4248 from V&E Antenna in Thornhill. I've got it mounted on my rooftop and I use a rotor to fine tune.
"Channel One Antenna" is an OTA/CCTV installer company that services the GTA and Niagara. Has anyone dealt with them and how was it?
Could you please post pictures of the install they did, especially the grounding of your antenna? We normally don't comment on our competitors but we had a few jobs in order to fix inadequate grounding on SkyTune installations. They don't ground the antenna mast and use a small piece of 18 or 20 AWG braided (i.e. speaker wire) rather than solid copper wire in order to connect the splitter used as a ground block to the indoor panel ground.I can recommend these guys who just did my install in North Mississauga. Let them know that Michael Lee from Mississauga sent you.
The grounding block should be outside your home, just before the cable enters your house and wired directly to a dedicated grounding rod for your antenna (the mast should also be connected to this grounding rod). There should also be a 6 AWG bonding wire from the grounding rod to your electrical ground to ensure the ground potentials are the same. See the thread Grounding Info & Standards: OTA/Dish/CATV/Telecom for details and further discussion on grounding.grounding to the same location as other items I already have in the same room.
