I received the modified Kitz Tech amp with the power injector.

I should do a test soon. I going to test WVNY-DT, W52CD and the weak Montréal channels at my location:

Global 46, Savoir 29, 62 and Télé-Québec digital 27.

I will report the results here.

I was going to get them from the place in TO that mlord mentioned, hopefully they have the 75 ohm end cap.

You will have to buy the terminator separately.

What happens if you don't use the 75 ohm terminator?

Any idea where to buy them?

You could get leakage or signal reflections.

I picked up a couple from Home Hardware on the weekend, but that may have been old stock. The Source should also carry them.

goforit...

Even Home Depot has the 75 ohm terminators - package of 10 under the Ideal brand. Maybe a few more than you need but they do seem to come in handy and they are not that expensive.

I live in Moffat ON and put up an CM4228 outside about 40 feet above the ground, i.e. around the tops of the trees at my place. I did not receive any better reception for DTV signals than my Mini-state which is in the attic. The cable run is rather long so I bought the CM 7777 pre-amp (the Mini-state is an amplied design).

I hooked it up and put the power supply as I read somewhere, near the TV which where my mini-state power supply resides. Coax run from antenna to supply is likely 100' (winds through attic and walls down to basement). Reception was no better. I checked all connections and cross connected the coax with the old antenna. The only option I had left was to move the power supply up to the attic to have less cable between it and the pre-amp. Remarkably that worked and I now get lots of channels (I will post the info in the other section). It's great but I'm confused by this problem. There is nothing in the documents saying there is distance limitation between the pre-amp and power supply. I did have one coax connector in-line to join two pieces but that was it.

I'm glad it is working but wanted to post this to see if any understands the problem and to help anyone else that might run into this.

That's usually what happens. But with a UVSJ, those reflections still have to bounce through the other band to cause any interference, so not as much a concern there as usual.

I finally installed an antenna outside. Not always easy when you are a renter!!
So I have two antennas DB-4 and Clearstream 4 that are almost identical for INDOOR use, but when installed OUTSIDE, C4 is much better for fringe reception. So now C4 is the one that I installed outside, wall mounted, aiming directly at a high building about 100 meters away but that is in direct line with best reception.

What can I use to improve fringe reception? The antenna is use for local (Montreal) and US reception. For now from US I get channel 3, 5 and 33. I'm guessing that a preamp would be the first option, but wich one? For exemple from ChannelMaster 7777 preamp is high gain but will it saturate local reception (I already have little ghosting on certain condition) so should I use 7778?

Suggestions welcome, I use ChannelMaster as reference but any brand and model will be good.

Bob_Mtl, keep in mind that KitzTech preamps are now considered the best price/performance combo out there now for preamps. See intravino's many posts for his very good findings in your general area of Southern Quebec.

The CM 7777 will block the power to the amplifier inside the mini-state antenna. Without power, it will block the signal.

Sorry to clarify, the CM4228 and CM7777 are completely separate from my old mini-state attenna.

The obvious answer is that there's something between your TV room and the attic which is blocking the DC power up the coax.

Probably a splitter, or bad coax connection somewhere.

Sorry. I misread your original post. I agree with mlord and the most likely cause is something blocking the DC power. It shouldn't matter how far away the power injector is from the pre-amp (within reason or course, if it was like a kilometer away that could be problematic ;)).

We have a Belgian member of our site who uses a Mega Amp preamp pictured in his post here:

See my comments about his pictured Wisi eb66 antenna here, as they apply to the preamp too:

If you Google "MegaAmp ULNA3018 and 3036 DVB-T/HDTV" you'll see a pair of European preamps that luckily cover the North American UHF TV band too. One outputs at 18dB and the other at 36dB. Without knowing if those specs on that web site are realistic, I'm just wondering if we may have found another great preamp.

Comments?

Maybe its another so-called good looking noise figure, but again, its around $200 CAD or more shipped for the 36 dB gain model (not sure 36 dB gain makes any sense!), just like the RC amps...:o

You could be right, but considering they only cost about a buck a piece, it certainly doesn't hurt to use one. If you decide not to use one, I would connect it as a band separator to remove the risk of the unterminated connection acting like an antenna. Actually, this is probably the best way to connect it regardless.

OK, so how do you connect as a band seperator?

Have the "Line" port as the input (antenna side) and the "UHF" port as the output (TV side).

So no 75 ohm terminator needed on the VHF port?

If you can find one, I would use it, but if you can't, you can probably get away without one.
