So will Global actually be broadcasting HDTV OTA, or is it just for the cable/satellite providers now? If so, what areas will be covered?
I've got my "Flying Arrow" aimed at the CN tower right now and my OTA set to channel 65, the channel Global was said to be using in Toronto. Still waiting for the Global HD signal to come alive today. (Oct 11th) Lets see if they can do it!



As for all the simsubbing..... they can't do that to you if you have your own OTA antenna.

Hey Jurassicjockey,

You should consider replacing the guy on the tower with a rotor. In the long run it would be cheaper, no bathroom or lunch breaks needed and it would also make changing channels a little faster. ;)

All joking aside, that is quite the setup you have there. What kind of DTV reception do you get? What amp are you using?

Yeah but he owes me a favour. ;).

The setup is two Televes DAT-75s, in the vertical stack for gain, with a CM 7775 preamp. I have a long cable run, so I used RG-11. I pick up the standard Buffalo's with 29 being the most problematic and PBS being the most rock solid. T1 comes in all the time on 15, and City only comes in about 60% of the time. I'm using a Samsung 151 receiver.

From what I read vertical stacking doesn’t really improve the gain very much compared to horizontal stacking. Did you ever try doing a horizontal stack?

The bigger antenna in that picture is a UHF/VHF/FM head and is fine for HD channels and will do a nice job for SD channels also.
That looks like a Channel Master 4242 or Delhi 929 model.

The small round one (mini-state) is less likely to get you maximum channel capability. They have actually discontinued making the mini-state antenna.

CM Quantum 1111: Mine, all mine!!!

Okay, I'm talking to Marv, who ran Marv's TV here in the Vancouver area for over 40 years until he retired a few years ago. He's done hundreds of antenna installations all over the Lower Mainland in his time but he's tired and his memory is fading. He tells me about an old antenna he's got in his barn, so I drive right over there and back up my pickup truck to the doors. Here's what he has:

One never opened, brand new in the box, shiny, fresh as a daisy Channel Master Quantum 1111 VHF/FM antenna! CM hasn't built any of these big beauties in quite a few years, and we figure this particular one is from the late 1980s-early 90s. CM went through some financial troubles over the years and dropped these from their product line. What a shame.

In a 1982 article in VHF-UHF Digest writer Bill Thompson said that hard core DX'ers back then were using either the Jerrold (now Wade) VIP-307, the Winegard CH-5200, the Channel Master 3617B, or the Channel Master Quantum 111X series (1110 through 1115), but that the CM111X series clearly had the best all around reception while the others led in some areas but not in others.

Now a CM1111 is mine, all mine! Tigerbangs, eat your heart out! ;)

This thing is the Cadillac of all VHF antennas, and I mean that in a couple of ways: first, it has probably the highest front-to-back ratio ever built (you WANT that in VHF but not so much in UHF) and second, it is a dual-boom monster that parks up on your roof like a 1960s Sedan de Ville! :D Instead of one front-to-rear boom it has 2, one over the other. This thing is built for huge wind and snow load but you have to have a stout mast.

The box was the old CM one with the colour spectrum printed on the side. When I tried to pick it up it disintegrated from mildew, old age, and mouse dining, so I laid the antenna directly onto the 8-foot box of my truck and it hung out an additional 1.5 feet. With the front extension added this thing is about 11 feet long. I haven't spread out all the dipoles and directors yet, but when I do I'll take a digital snapshot and post it here.

I asked Marv how much $$$ and I almost fainted when he asked for an arm and my right reproductive pouch, so I looked inside his barn and pointed at a few things. After some dickering I drove away with these too:

1 - Channel Master 0094 PreAmp, which fits inside an underbelly trap door of the 1111 antenna and is an integrated 300 to 75 ohm balun, FM trap, and preamp. With this preamp riding on an 1111 Marv estimates about 35db gain! He says customers in the Lower Mainland, including on the North Van side, and out in Mission were clearly getting SeaTac VHF stations with this setup.

1 - old Delhi UHF 4 bay Bowtie Reflector in good shape that looks a lot more like a CM 4221 than a new Wade 4BT-1483.

1 - coil of shielded 300 ohm balanced cable (I'm sure I don't need it, but somebody might since its shielded).

1 - big box full of clamps, splitters, brackets, paraphernalia, doodads, geegaws, thingamajigs, whatchamacallits, and other stuff.

All right, I am a complete geek who might have had a bit more money than sense that day, but at least now I own the best deep fringe VHF and UHF antenna gear a guy could ever want.

I have no place to mount it! My north property line has a 150 foot Douglas Fir and a bunch of red cedars, and the south property line (in the way of SeaTac signals) has a row of 60 foot red cedars. I would need to put up quite a tower here... unless... I could mount those antennas up on top of the 150 foot fir! Wow, the reception would be spectacular!

Naw, I've been through that idea from a-to-z and it won't work... ;)

Anyway the wife and I would like to move out of the metropolis to a more rural area so a tower would be more feasible at that time. Also even when the SeaTac and Canadian VHF stations wind down over the next several years I'll still have the amazing FM radio pull of that 1111. We love KPLU-FM but haven't been able to listen to it since we dropped cable tv.

Some day I will take down my BEV dish and fork over my last monthly gouging to them, and I'll proudly raise a mast holding my Channel Master 4228 UHF 8 bay Bowtie Reflector and my Channel Master 1111 VHF/FM antennas.

It will be glorious... (wipes a tear from the corner of his eye) :D

that antenna is a Channel Master 4251 UHF antenna, and it was the best consumer UHF antenna ever built: it had the ability to pull UHF stations when NOTHING else could. Ugly: YES, but I wish I could get one today!

Where did you find those parabolic antennas? The antennas pictured are NOT channel Master 4250s or4251s????
Yeah you're right! I took a closer look and found out from a Ham buddy that the P-7 P-5 UHF TV television parabolic antennas were made by Antennacraft whom were in competition with Channel Master's Para-Scope 4250 & 4251 seen below. Too bad non are still made anymore !

My monster antennas and my monster trees Pt. 1

As promised, here's a photo of my never used, brand-new-in-the-box 1980s era Channel Master Quantum 1111 VHF/FM antenna opened up for the very first time. I rested it on a wheel barrow beside a 1 gal. paint can and a basketball to give a sense of its big size. I'm really pleased with the solidity and good design of it (note that it has not one fore and aft boom but 2: a lower and upper one!):



Here's my Channel Master 4228 8-way UHF bowtie reflector & Winegard AP8275 preamp sitting at the south side of my house while I figure out what to do regarding where to place it (you'll see what I mean shortly). Interestingly its resting against aluminum siding and pointing towards 3 huge Red Cedars and a house in behind them that has an aluminum roof, yet I pick up lots of analog and 2 digital stations from that location, with a rare dtv lock to a Tacoma WA station:



This 150 foot Douglas Fir on my north property line towers waaaaaay above the Red Cedars to the left and the Green Elm to the right, but I'm not sure if you can tell that from this perspective. Its the tallest tree in all of Delta, BC and an arbourist analyzed it and said it is in perfect health. I actually thought about putting my antenna gear up on top of that Fir until sanity set in (cost of hiring climbers to do it was high, but also climbers didn't feel qualified to do antenna work and it would be awful if they came down from installing it and I found out later that they had gotten something wrong!):

CM Quantum 1111

Stampeder, better not mount that on your house. Either your house's foundation will sink or your house will appear to be only 250 ft2. Ha Ha.
That thing is HUGE !! I could run cable from Windsor to your antenna and still have enough signal in the line to watch tv !!!!!

With the preamp installed it apparently has about 35 db gain! I figure if I had taken a photo of it at night from the front down low it would look a bit like this:
