The HD Stacker reception

post #1 of 14
Thread Starter 
Hello everyone!!!

For the past few weeks I decided to cut the outrageous satellite bill off. I've been doing some reading here online and asking a few people in the area about OTA reception. Anyways, I made the initial decision and purchase the RCA ANT751 placed 15ft high. I was very impressed to see there is reception of a few channels from towers almost 50 miles away so I added a Winegard AP-8700 Amplifier and see a little further. The Amplifier added a few more channels which made me happy.

This was all done according to tvfool.com

Now, it was really good to see this reception so I decided to experiment a little more and purchase Denny's HD Stacker and complement it with the Winegard AP-8700 Amplifier and place it 25ft high. Now, to my surprise the reception was worse. I lost a few channels 50, 45, and 29 channels went away, not counting channels I had really good reception went to very weak reception. My intent here is to receive as many channels from 160 to 170 degrees.

I know I'm not an expert, but at the same time I think I know what I'm doing. All my cables and connections are Eagle RG6 quad shield. So I don't see any reason why the HD Stacker is giving me such low performance. The RCA ANT751 does a better job, why?...

I just ordered and received an Kitztech TV Booster KT-200-COAX TV Antenna Booster Remote Power - Coax Fed and see if the lower noise factor makes a difference.

Do you guys think my problem is the HD Stacker antenna? At this point I'm very closed to send the HD Stacker back and continue with trial and error.

Doing some further reading I found the The DAT HD 75 BOSS from Televes. Has anybody had any experiences with this product?

I am seriously considering stacking Xtreme Signal HDB91x and the Antennacraft Y10713. Does it sound like a good idea?

Do you guys think the Channel Master 5020 is a better idea?

If you are reading my post, thank you for your time and I hope some of the more experienced guys can guide me on OTA reception troubleshooting.

Yes, send it back. No, do NOT continue with trial and error. Your situation is not one that needs trial and error, it needs logical analysis.

ALL of your available channels are UHF, you have ZERO VHF channels available to you. Therefore, you would do best with a very directional UHF antenna such as the 91XG, DB8e, or another long UHF Yagi or 8-bay panel UHF antenna. You have no need for an antenna with the longer VHF elements.

The lower noise figure of the KT200 (over the AP8700) is unlikely to make a significant difference. Your most immediate problem is the strong signal from KRWG which will likely send most pre-amps, especially after a high-gain UHF antenna, into compression. This will result in desensitization of blocking of weaker signals. Neither amp you have is likely to do well in this situation without a deep notch filter for channel 23. Quite honestly, your best bet would be to re-purpose a PCT or Channel Master single output drop amp as a pre-amp. Not may other pre-amps can offer such a balance between decent noise figure, medium gain, and overload resistance.

Your location is a difficult one due to the hill or mountain that the desired transmitters are behind and your proximity to that PBS station. Expect significant challenges and be patient in trying multiple mounting locations.

Thank you ProjectSHO89, I appreciate your input on this thread. As you mentioned, I actually have a Channel Master CM-3414 just sitting here and I'm going to try it out as you mentioned since the Kitztech TV Booster KT-200-COAX did not do any better than Wineguard AP-8700.

If this does not have any reasonable changes, I will take the HD Stacker down and send it back today, I could utilize those dollars to purchase the Televes DAT HD 75 BOSS since it has a pre-amp which it has an automatic signal balance mode. Sounds like this company does very well in Europe and South America.

The HD Stacker is indeed unnecessary if there are no HiVHF stations. A good long range UHF antenna is the Winegard 9095HD, or the Antennas Direct 91XG. But you may also consider the Extreme Signal version from Solid Signal, their 91X model. Priced at $49. As far as the preamps, those Channel Master dist amps can be used as a preamp as long as you have a remote power supply. You could try the remote power supply from the Kitztech before you send it back, just to see if the CM dist amp works. Then order the PCT/Channel Master power supply from PCTstore, Channelmasterstore, or Amazon whichever cheaper. Usually around $599. And the single port amp from Channel Master may work better at 15db if the other version does not. I believe it is CM-3410 model. But those Kitztech preamps are very good amps with a low noise figure. I have a mix of strong and weak signals, and both Winegard versions had overload and pixilation issues for me. The Kitztech 200 and original CM-7777 did not.

Do they now have a U.S. distributor for Televes antennas? They are reportedly good performing antennas, but a bit pricey and difficult to purchase domestically. Can you provide a source?

I found them for very reasonable price at ebay.
Just do a search or call them directly at their site I provided.
They have a store in Englewood, CO.

The Televes DAT-75 with the built-in pre-amp will overload from KRWC. Specifications state a maximum signal input of 75 dBuV (-34 dBm). KRCG's signal is predicted to be more than 15 dB stronger than that.

If you can re-locate that CM3414 to the mast head as a test, you'll know if a distribution amp will work for your situation.

Time to stop looking for magic bullets, there aren't any.

MCM has a triple boom yagi similar to the Televes for $39. Stellar Labs. And also a version with a built in amp for a bit more. But I'm not sure if those triple booms actually provide triple the gain

Sorry guys, I've been getting out late from work and the rain hasn't allowed me to get on the roof yet.

I was reading on Channel Master CM-5020, does anybody has any experience with these antennas?

Do you guys think a very directional yagi UFH antenna with an attenuator could also work?

ProjectSHO89, what do you think? You seem a very knowledgeable guy on this matter.

You have NO VHF stations available, so the 5030 is not the antenna for your situation. Any of the suggested UHF antennas would be a good choice. (I personally like the 91-XG)The 3414 amp you already have is also an excellent product & will NOT require attenuation. The 3414 is an amazing performer & difficult to overload.

I agree here. Get a 91XG UHF antenna or the cheaper Extreme Signal version. No VHF antenna needed. Use your existing CM-3414 as a preamp with a remote power supply. Put terminator caps on any unused ports. Probably the best option.

Well, today I had a chance to get on the roof and I did as ProjectSHO89 suggested. I got rid of the pre-amp and replaced it with the Channel Master CM-3414 and the results were not as expected. Channels NBC and ABC were gone. I guess that route is not the problem. I took down the HD Staker down, enough is enough trying to get some performance out of it. It is packed and ready to be shipped back to Denny.

Now, what is better choice between Antennas Direct 91XG or Solid Signal HDB91x?

Both of them look the same to me besides the price...
post #13 of 14
The 91XG is a proven performer, but the Extreme Signal version does appear to be basically the same.
post #14 of 14
The 91XG has been around for years. Lifetime warranty.

Solid Signal just started importing the Chinese antennas and putting their name on them this spring. 6 months warranty.

Who knows? Either will likely perform similarly.
