To get a good ground you need a grounding system that reads 25 ohms or less, most systems are using 8 foot 5/8 inches thick rods, that's the only thing i use. You might not have the equipment to measure it but I would question using a 4 foot one that were on clearance as they might be...

You may just have to go with Dish or DirectTV for your OTA channels unless your willing to spend a lot more money on a tower, rotator and new antennas. If money not an issue then I could see you getting additional stations, but the MANT940 isn't going to do much for you as it's range is around...

Altitude is 950 ft at ground level.

No easy answer on whether you'll get it as it mostly depends on your location and anything in the way of the signal. My case I'm on the highest point in our county which helped . Could have gone higher with tower but for power lines and I was concerned it might reach them if I added another...

LIST: POOR GROUNDING

If your talking about the 4251, I have one at 35 feet and I have no problems getting solid 24/7 programming at 90+ miles. Great antenna if you can find one.

How are you jointing the two antennas to the CM7777 as I show there is two different models that you might have as one with a single input and a second with both VHF and UHF.

I'm guessing with three 722's that you also have each one hooked to one or more TV's so does the problem happen on all of them? If so then like Iceberg suggested I'd be checking all your connections. Also are you feeding each receiver with a separate cable from the OTA or with a splitter or some...

If your still looking for an older VHF antenna you might check out Warren electronics as they have some left over antenna per their web page, maybe one would work for you. http://www.warrenelectronics.com/antennas/cl_ant.htm

Another point is there’s splitters that seem to be good and others not so good, you didn’t mention what brand of splitters your using as some have different ways of being build . One brand is the Channel Vision HS-4 4-Way Splitter/Combiner that seems to get good reviews on its performance so...

I wasn't even talking or looking about any insertion loss, it was more about keeping the installation simple with less items which should make it easier to troubleshoot.

I'd get a larger 4 way splitter and just rid of the other two, also it might help us if we had a TVFool map or zip code and what stations that your missing.

Since you appear to not own the antenna from your last posting have you checked to find out just how much the owner will allow you to do?

Since your antenna is UHF only, why not just go with a Winegard AP 4800 which is only a UHF preamplifier and has 28 db gain with only 2.7 db noise. You don't need the VHF part. http://www.solidsignal.com/p/?p=3561

I'm thinking you got more damage from the lightning strike,either it damaged your TV or other equipment that you have inline. I'd first try another TV set hooked directly from the antenna, with and without the amplifier to see if it makes a different. Also last option you might think about...

I've been using different Channel Master amplifiers for years and have never had an issue with any of them not working, only thing that I can think of is either something is wrong with the your setup or your expecting too much of it for your location. Little more information about your problems...

Since the signals today are digital, snow and interference will not appear in a digital received TV picture. One can help or might not, but if it's a weak signal the picture won't lock and you can have pixelation problems.

They just forget to tell you that it needs to be installed on a 6,000 foot tower. Otherwise it's JUNK!!!

As long as you tie it back to the same bar in your panel and depending on when your house was build it's completely correct as long as they are within 5 ft of the point on entry of the pipe. The following site might also help you. Grounding Satellite Dish and Lead-In Cables

Aluminum is a good conductor so I'm not sure about that, but if you had a direct hit on the tower no amount of grounding is going to totally protect electronics from it because of the overall cost factor, but a direct megawatt strike is a fairly rare occurrence. In your case I'd go to Home...

I would only go with an 8 footer as I'd think you'd have a better chance of getting into the 25 ohms range with it. There different thoughts on how to ground and bond a tower and if I were you I'd search Google with "grounding and bonding tower" and read the different postings. My system I used...

Here's a Rohn model on Ebay that cost a few dollars more but I think would give you a solid mounting system as compared to the other one. Genuine ROHN UHF25G Side Arm Mount for UHF & FM Antennas - NEW! | eBay

And that cable guy doesn't care and he had NO ideal what he's doing when it comes to grounding. The minimum most likely should have been an 8 footer rod and the only way to know for should would be to measure it. AS far as the cable in the basement that's what I do as the my tower is on the...

Nothing is stopping you from doing that, but you'll stand a good chance of having a ground loop which will give you all kinds of problems since by keeping the two systems separate it can create a dangerous potential between them.

It's not grounded unless you have a ground rod next to the tower and then tied back to your house ground.
