Thanks to Kro for this information:

The Winegard UT-2700 is an adjustable trap for UHF 470-810 Mhz, with two adjustable filters:UT-2700 ADJUSTABLE UHF TRAP

Trap may be tuned over the frequency range of 470 to 810 MHz. Features two separate traps. Both may be tuned to the same frequency to reduce it -15 dB, or separate frequencies to reduce 8.5 dB. Can be mounted indoors or out. Passes VHF frequency; AC/DC passive. (Tunable traps require the use of a scope, analyzer, or signal level meter to tune accurately)http://www.winegard.com/offair/traps.htm

Hello. I built a 4228 clone last summer and mounted off my chimney.Works Awesome!!I had 45' run of cable. All my channels were over 65 miles away and I get 75 to 100 % on Buffalo channels. Pick up all Rochester channels no prob If I turn the antenna.I bought a new HDtv and had to add 50' of cable.WELL I lost NBC ABC.I'm just wondering If a preamp would work in this case?And I was wondering can you put a ab cable switch in and have the one cable go to my original tv " 45' "and the other go to my new tv" 95' " would the old tv be like it was when it was switched to it??And Also I planning on putting a CM 9521a on when the nice weather comes to pick help pick up channels.Thanks

Welcome Frost55,

You don't need an A/B switch. Assuming you are not within a few kilometers of the CN Tower, you need a pre-amp at the antenna and common 900 Mhz splitter. If you are extremely close to the CN Tower, you can always throw an attenuator into the line going to the old TV, after the splitter. If you can shorten the run going to the new TV, to save a lot of $$$ you could try a distribution amp instead of a preamp.

This way you will have constant signal to both sets.

Does this help?

cheers!

By the way, it helps others to help you if you put your general location into your profile. :)

Hi,

I am looking to buy compression connectors for some rg6 cable i have lying around. Where is a good place to get the thomas and betts ones, I was told these are the best and used by rogers.... is this true, anything better and/or cheaper?

I am in Scarborough and would like to pick up in store as I would prefer to do this during this week, I'd prefer stores in markham and scarborough...

I can borrow a stripper and compression tool from a friend so I don't need those!

Thanks

Mighty nice friend! I wish I could 'borrow' a stripper! :)

I'm not sure about the east end but I usually visit the Electronic stores on Matheson for my compression plugs. You can find all your hard-to-find gizmos at Dixie and Matheson.

I purchased the 4228 because I had read that it was the best commercial UHF antenna on the market. Notwithstanding, it is getting inferior signal than my diy antenna.

I can only think that this has to do with overloading from channels 17 and 35, am I correct in assuming the foregoing?

Although my DIY antenna is satisfactory, I would realy like to get the CM-4228 working.

Would a filter such as UT-2700 help my situation? I checked EBAY and I didn't see anybody selling this, anybody know where I can buy one?

BTW, I am using a CM-7777 pre-amp.

Yes you are correct.

It might work for you but since i bought it for $28.99 winegard more than double it's price. I would recommend you to ask Tin Lee what they can do for you. Just ask them for a notch filter for 17 and 35 of at leas 12 db (each). The other option would be to try the ge pre-amp intead of the 7777 it might be enough. And by the way the 17 is probably causing 80% of your problem so just a notch for the 17 might also be enough.

Kro,

I sent an email to Tin Lee but the price is a bit steep (20$+ more expensive than the UT-2700 from summit source and summit source includes shipping).
In any event, it might be better to get a tunable filter rather than a fixed one.
However, I read on another forum that specialized equipment is needed to properly tune the UT-2700.
How difficult was it for you to fine tune the ut-2700?

Yes but the Tin Lee product is High Quality and it's pre-tuned, let's say that i'm 97% confident that with it you will have a perfect reception. If I would have to buy today I would go for the tin lee solution. (for 20 to 30$ it's worth it.)

How difficult was it for you to fine tune the ut-2700?

How I did it: I used my old TV in the basement hook a simple bowtie (About anything will do) the idea is to get a snowy with color picture on UHF 17. Ideally you need a very stiff non conduting screw driver since I was not able to find one I completly cover one of my screwdriver with electric tape (Even with that the screwdriver still had an effect on the Ut-2700). Then you play around with the screw until the signal is kill. There's two notch (two screw) so you do the same with the other for UHF 35. Took me about an hour to tuned it.

Thanks Kro,

I have ordered from Tin Lee, I should receive the filter sometime next week. I will post my results as soon as I receive it.

I am very interested by your eventual results, because i have a similar problem. I got a quote from Tin Lee, but I am hesitating because it is a lot of money. I think i would rather go with the adjutable one, in case 35 and 17 are not the only problem.
Anybody think that Global Montreal analog (46) could be a problem for tuning in Fox DT(44)?

I purchased the 4228 because I had read that it was the best commercial UHF antenna on the market. Notwithstanding, it is getting inferior signal than my diy antenna.

I had the very same problem with a NEW 4228 versus a 20 years old rusty 4221.
But I just ordered the Winegard dual Notch filter to "almost kill" the 17 and 35 from Montreal; I will tune the notch with the analog tuner in the TV

Here were my results with the CM4228 and CM7777 pre-amp (attic installation):
2.1 = 83%
3.1 = 48%
5.1 = 80%
6.1 = 70%
33.1 = 65%
35.1 = 75%
44.1 = 49%
57.1 = 59%


Since then I purchased the Bandstop filter from Tin Lee (CR7 2-ch. 35/17 (20)), these are my results:
2.1 (19): 95%
3.1 (52): 80%
5.1 (14): 85%
6.1 (20): 85%
33.1 (32): 82%
35.1 (42): 80%
44.1 (43): 60%
57.1 (38): 55%

Notwithstanding the foregoing, channels 17 and 35 are still coming in very clearly. Perhaps the 20db attenuation on each channel is insufficient?

The following analogue channels are coming in very clearly:
10, 12, 17, 22, 29, 33, 35 and 46.

What would be the best procedure to follow in order to get better signal on channel 44.1?

I'm also planning on installing the 10Y13S during the coming weekend, I'll post my results here afterwards.

BTW, I would highly recommend Tin Lee, they have excellent customer service.

I installed a Distribution Amplifier (10dB gain, 4 outputs) so I can feed 3 ATSC tuners and FM's.

When I fisrt put it in, on a clear day, I was really Impressed. I had much better reception on all channels over the splitter i used to use.

But, on bad weather days, my reception is Much Worse, than before.
My distribution amp seems to Amplify the BAD effects of weather, more than the good signals.

Anybody got any ideas?

Well, my indoor Zenith Sensor served me well to get OTA HDTV...but the darn tree has started to bloom and now the signal has gone away. I'm obviously not going to wait till winter to resume my HDTV watching. Here's a question:

I currently have Videotron and I noticed that they are using some sort of splitter for some odd reason to get the cable into my house like ALMOST like this but not exactly (don't have ladder to check):
http://assets.twacomm.com/assets/1987187507/product_images/15158.jpg

on the left to pole which is where the cable comes from
on the right empty

The middle one goes to the house.



Would it be possible to use that empty one to plug in my outdoor antenna or is that a bad idea? :)

It's a very bad idea. A cable tv system use the same frequencies used by tv/radio broadcasters and public service and commercial radiocommunications. An antenna pluged on the cable installation will create interferencies on the cable system to you and your neighbors and will also create interferencies to airplane and public service radiocommunications caused by catv cable signal leakage.

Here's another DHC thread discussing the issue:

Thanks for the tips guys...looks like I'm drilling another hole in the side of my house.

Hello,

How would I go about doing a HDTV OTA setup like this?

And is having two antenna's facing two different sides a good idea?

I am mainly looking for what I need in point A and point B.

I'm not sure if doing a splitter on A and then reversing it on B end would actually work..

thanks!

Hello Folks....

I have two DB 4 antenna's which I was thinking of mounting on a 10' 1-1/4" mast on my chimney. Question I have is what should I use to combine both the antenna's to allow me one lead of RG6 to the ground block?.

Thanks in advance,

HQS
