All these tv channels... and nothing on? Ottawa has access to hundreds of television channels, ranging from local services to U.S. networks, to specialty channels, and everything you can think of in between. We've included links to cable tv, hd signals over-the-air, digital tv and satellite tv stations as well.
(basic cable listings for Rogers customers)
Depending on where you live, and how well your antenna is placed, you may be able to receive these channels over the air in Ottawa
The best VHF antenna would be the same log periodic antenna, however this might be out of the realm of the amateur antenna maker. The dipole utilizing a section of 300 ohm twinlead works quite well with for both VHF and FM radio.
Aluminum foil can be used also, if put on a wall at ceiling level and covered with wall paper or paper it makes an excellent antenna, this may also be used for low power transmitters with an impedance matcher (combination of variable inductance and capacitance)to arrive at a low standing wave ratio.
An excellent reference is The Amateur Radio Antenna Manual, this is in most libraries."
4 CBOT (CBC)
9 CBOFT (Radio-Canada)
13 CJOH (CTV)
14 (Omni 2 expected to go on air soon)
34 CFGS (TQS)
40 CHOT (TVA)
43 New RO (CHRO)
60 Omni 1
65 City TV
This list does not include out-of-town signals such as Watertown NY (PBS, etc).
There's also supposed to be a retransmitter of CKWS Kingston in Smiths Falls, although I have not been able to pick that up (may be too weak to see in the Ottawa market).
For some strange reason, I'm seeing Global on channel 27. Not sure if this is the result of a hardware glitch or if Global runs a strong channel 27 transmitter elsewhere in eastern Ontario.
As far as the one comment about using 300-ohm "twin-lead" cable for an antenna, this can work well on many channels but one has to consider "wavelengths" of TV frequencies. Wavelengths get smaller as the TV channels get higher.
It may be better to purchase an amplified "rabbit ear"
and loop type
antenna for local reception. A Jensen amplified indoor antenna pulls in the UHF channels better than unamplified rabbit ears or loops. Haven't tried the bigger antennae such as the "giant smoke detector" units that retail at Radio Shack and elsewhere, but have heard these can work well. However, I have not yet been able to pick up signals outside the Ottawa region such as Watertown.
Outdoor antennas will generally be better than indoors. Also, the higher the antenna off the ground, the better.
