I am looking to have someone install an antenna at my home in Mississauga, so far, I have contacted 3 companies, The Antenna Guys, Toronto HD Antenna Installers and Dr, Antenna. Has anyone heard of these companies? If so, can anyone please tell me if they are any good? A couple of them sound good, Dr. Antenna offered a two year guarantee to cover any installation issues but the guy said he would use my existing cable connected to my TVs, however, I read in a form that a cable run should not be longer than 50 feet otherwise you will get signal issues or something along those lines. The same guy says he has a strong antenna that streams both UHF and VHF, the other guy says he prefers to use the DigiWave antenna as it does a good job pulling in channels, either way the antenna will be installed on my existing tower which with a mast will sit higher than my roof top. Any advise or recommendations would be greatly appreciated or if you know someone that you trust will do a good job, and they work within the GTA, please let me know?
