The allotment in the LOU (Letter of Understanding) is omni. As long as WJW conforms to the allotment (625 kW ND) then they should be fine.

Pretty sure that they are no longer running CBLT (Toronto local) news anymore, just the national stuff, at least weekdays.

Don't know about the dramas, tho...do you remember the names at all?

I watched the 6 pm news on Monday (CBET 9) & it was out of Toronto (all the major headlines/WX & sports), though thy did have a side story on Windsor too.

I have a very short memory, so no names, though the Talk Show @ 4am was with a guy in a sweater kinda reminded me in a way of a young Adam Sandler, that did a Lenoisque comedic monolog, about (Canadian) Thanksgiving, as it was this last weekend.

I do get blips on 31 up here especially during this past band opening, yet never was able to lock CITY 31.

Just did this experiment, since a few of you claimed I should be pulling something in on this antenna....



I obtained a new balun (PX brand commercial), & installed this direct to the set witn no (inside) amp, & threw it in a nearby indoor ficus tree & aimed at Cleveland.

Of course no 17 or 23, a pixilated 55 & 25, & a fairly decent 3, & 43, & a solid 5 & 61... & the real surprise was a pixelated 8, as this is a UHF Antenna, & mentioned on a previous post I'm not getting 8 from my large 120 mi VHF/UHF attic Yagi.

I'm still @ indoor second level at this point, though would a reflector give me that much more gain, & which one would yeild the best results, the chicken wire (above) or the cut to length below?

When I talked to an antenna designer he said that they create the antenna then figure out later how it works if it works then write the technical data to explain it. This was years ago and procedures may have been changed.

So Trial & Error? Just didn't want to start throwing good $ after bad, I do plenty of that enough. Wanted to use the better theory here & tweak from that. Unless resonance, I really don't see why the percise cut reflector elements would do better than a sheet of chicken wire stretched accross the back of it, or the reflective blanket for that matter. Years ago I remember my dad placing aluminum foil under the attic yagi to get out of town football games, he's not even sure if that worked. The PVC framework seems rigid & secure.

I think we have our answer about the news being from Toronto - Monday was indeed Canadian Thanksgiving, and I don't believe CBET does local news on major holidays. They must feed down Toronto on those days.

Susan Pedler and company were surely back Tuesday.

Whew! I'm not hallucinating the entire Windsor news operation.

31 out of Woodstock is a LOT less powerful digitally (20 kW) than it was in analog (1000 kW). I'd be surprised if you got a lock between now and when WJW moves to 31, except perhaps during very, very favorable tropo conditions.

Look at my set top VHF-UHF which worked great in Berea except on WKYC analog. You might do as well with a dozen coat hangers bent up for a reflector, or maybe cruise around on trash night and try to find some steel grate type fridge shelves near a useful size. Take a look at different UHF and UUHf designs, you see horizontal elements on reflectors, some bound at edges, some not perhaps only for strength when exposed to winds, or in the case of the set top design seen, to prevent bending in case of a fall. After seeing some designs with a bent reflector, maybe a piano hinge in the center to experiment on some weak signal enhancement.

Really if it's just reflecting, what was the issue with percise reflective elements & attachments? I recentl;y dismantled a Yagi, probably could have used part of that for the reflector. Though they are shown using a chicken wire mesh as a reflector & a specific 30" x 40" grid, was thinking it was for some sort of resonance in design, as I'm not that familiar with this type of antenna.

Which is exactly why we have to protect Canada, & wouldn't this interfer with WJW during openings?

Trip covered this earlier. There's a Letter of Understanding that allows both CITY-TV-2 and WJW to use 31...and at the time, CITY-TV-2 was 1000 kW analog. It's a LOT less powerful now after it went digital at the end of this month. I suppose trop openings could carry it farther, but day to day it's a lot less likely to interfere with WJW's 600 kW here.

I'm not sure what you're trying to say here.

Exactly. I just didn't know they fed CBLT's local news on hoiidays.

I have a spreadsheet with Yagi element lengths for the various TV channels (back in the analog days). The active elements were tuned to the visual and aural carrier frequencies while the reflector was tuned just below the two active elements ("below" is a larger element). The spacings between the elements were important as well.

I'm a bit dissappointed in this one, the one I installed for dad about a year ago could not take the wind load this past weekend, a couple of the elemets (ones with the aluminum wings) snapped off at the (blue) plastic at the boom. The plastic seemed very brittle & aged for only being in service for year. As far as I can tell nothing could have hit it.

No diminished signal, so I think I'm just going to leave it.

That's interesting. I installed the HBU55 on my roof last year, and I took it down and replaced it with the HBU33... a much smaller antenna, and I noticed no change in reception. The elements on the HBU55 were gigantic. I haven't had any problems with the HBU33 with wind. However, Saturday was so windy that it blew my satellite dish off just enough to get no signal. All the bolts were as tight as could be. It's just that the tripod wasn't on a stud below, so yesterday, I worked on nailing some 2x4 blocking between the roof trusses and making sure the mount screws went through the wood blocking. Now it's really secure.

I felt the Boom was too long to handle When I installed it he requested it to be about 18" higher (trying to catch ION) , so I installed another mast. Being in proximity to the edge of the roof instead of the center I thought if anything happens, he can get someone else to work on it.

As this again is in a troubled area below the ridge, we felt would be better to go with the HBU55, if not for WJW & WOIO we may had ditched this antenna & opted for a UHF only, though he has a FM set on it. I don't know if I'm going to replace it or not but seeing how cheaply it was constructed I'd be hesitant to get the HBU33 also. I'm taking the Blue plastic element holders aren't replacable? (really haven't had a chance to go up to see how they are attached to the boom.. i forgot already).

I likely will not do anything till next summer, just getting too cold to work now.

My 32" Sony tube is having issues, the tube takes about 10 minutes to get a picture, plus toggling between video/tuner modes produces a black screen for a minute, now the Video1 & Video2 are going black randomly, only a matter before the tuner starts... as my STB is set to Channel 4.

As I commented before the manufactures have cheapened up on the tuners in the last 10-20 years as most of the the sheep have flocked to Cable, there was no point to put a great OTA tuner in the set anymore. Are there any exceptional, & any to avoid as far as sensitivity? I avoided buying the Apex STB as the tuner was somewhat diminished when I tested it.

Maybe the birds were perched on the antenna elements and bent them.

Elements (only about 8 inches) were not bent, it was a clean snap of the blue plastic... they are broken off, not sure if it can be repaired as the manufactures don't seem to offer any replacement parts for these. Noted that the Element is held in to the socket on the blue plastic by a phillips screw, though I'm not sure what holds the plastic part (if I can get a replacement) to the boom. He only showed me one element, though another was gone with the wind or perhaps laying in the bushes or leaves.

Claims they weren't hit by branches, I didn't find it all that windy, unless it caught those aluminum wing reflectors just right.

This will be the 4th damaged antenna since 1987, I had just cut one of them up for scrap, there is one in his attic (emergency use) & one in mine for my second floor set(s)...... I'm getting tired of going up there, if you remember last year, I had water getting in the feed line to the attic splitter.

It takes some amount of force to bend those elements but to break them off you have to bend them back and forth many times unless they are breaking off at the junction point of the main frame. That would in my opinion take a very hefty branch to do the deed. I tried to bust those elements off when discarding my old antenna and it was a real hassle. Also water can be prevented from getting into the feed line by several raps of black plastic electrical tape over the cable connections. This is how they do well pump connections (220vac) and industrial power transformer connections (69,000 volts) allthough with the power transformer connections they build the tape up in layers to several inches thick. I watched the "pro tapers" due this and yes they went to school for it.

When I scrapped out one of the damaged antennas this summer (& yes in this economy, being unemployed it unfortunately is worth my time to run things up to the recycler), it was an effort to break it up, this broke at the plastic mounts on the UHF portion, & the blue plastic seemed very aged & brittle for only being a year old.... the elements themselves aren't bent or damaged.

Here is an update on my OTA issue with WVIZ in South Euclid. I have two TVs wired to the same rooftop antenna. On one of them, WVIZ comes in at 71. On the other one, it barely comes in and can't hold the signal. I have no idea why I would have this much of a difference! Obviously it could be set related, but that's a pretty strange difference.

Thoughts by anyone?

I'd guess the usual suspects and check the splitter, cable, tuner.

Once I took out the splitter, it improved to a steady 40s, which makes it possible to watch. Still not the level as the other room, but good enough for now.

Anybody else lose signal on WOIO (19.1 & 2) this afternoon?

I turned on WOIO at about 11:30 am and signal strength was very low, and when I turned it on again at 1:00 to catch the Brown, signal was gone. I checked again at 3:00 and still no signal.....

It's back on now (5:00pm) with 86% signal - anyone else having those problems today?

No problems during the week, but the weekend before this current one we were having much pixelization.

WEWS was a different story - every night but Friday, Jeopardy was barely watchable.

I agree with the others about the splitter - we were having similar problems on our second TV also, so we changed out the splitter and that seemed to fix the problem.

Good luck!
