Curiously, it seems that I can get a clear TV signal when I first turn the tv on, but that only lasts for a few minutes, and then it's gone.
|
That's odd; I wonder if the TV itself is causing interference. Some streaming devices that attach to the TV, like the Amazon Fire TV, can cause interference.

All my AC appliances here in the apartment are two pronged and with one prong wider than the other, so can't shift them over.
|
I understand that, most AC operated equipment has 2-wire polarized plugs. I was asking about the wall receptacle that you put the plugs into. A 3-wire wall receptacle can accept 3-wire plugs that ground equipment if it has it, and can provide a ground for equipment that doesn't if a good cold water pipe ground isn't available.

The only channel I'me interested in seeing for the late night news is CFRN (CTV) 3.1 The only one I can get right now is YES-TV, 30.1 which holds no interest for me at all.
|
CFRN is on real channel 12, which is a VHF-High channel. CKES is on real channel 30, which is a UHF channel. VHF-High channels have more noise interference than UHF channels.

for my antenna, right new I'm using a length of speaker wire to extend from one side of the room around the floorboards to where the tv is, and then into a coaxial connector and into the tv itself with another short length of coaxial cable.

Speaker wire?
Unshielded speaker wire?
That makes a very good antenna to pick up noise interference.
You should use only coax from the antenna to the TV antenna input jack, to reject interference.
What TV are you using?
A grounding block is not REQUIRED for an indoor antenna, but sometimes it helps to reject interference.
If the antenna is outside, the coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC in the US), the mast should also be grounded in a similar manner to drain any buildup of static charge which will tend to discourage a strike, but the system will not survive a direct strike.
