HD Stacker Antenna Questions and Answers

Question: Ask your HD Stacker question: Is this antenna omnidirectional? The picture on your website doesn't appear to have a rotor system.

Answer: The antenna is directional. All high performance antennas are directional. You only need a rotor if the TV transmitting locations are in various directions from your location. Many times all of the transmitters are in the same direction so a rotor is not needed. You can check transmitter location at the FCC maps >.

Question: Denny No offense intended but how do I know your HD Stacker antenna works as good as you claim? I've been burned once and bought a bad antenna that doesn't work and don't want it to happen again.  Is there anywhere in the Denver area I can see one?

Answer: No offense taken. You can visit our customer user review page >. However, we both know product reviews can be fictitious. Our user reviews are from real customer's. One reason I posted so many user pictures on the user review page is to establish validity. Hard to get pictures of that many HD Stacker installations if they're not being sent in by satisfied customer's.

Best Regards, Denny

Question: Hi Denny. I've read on some posts that the Stacker's VHF and UHF antennas are joined by twin lead. Since twin lead is 300 ohm and most people use 75 ohm coax, there is a 4:1 mismatch. Does the antenna come with a balun to compensate for this? I assume there is also compensation for connecting two antennas using the same transmission line as appears to be the design of the Stacker.

Also since UHF is more affected by line of sight conditions, why is that antenna located beneath the VHF antenna? It seems that optimally it should be the other way around. Can these be switched? I have a 20 year old outside RS monster antenna. The TV is now pixing more than previously, and I am considering a Stacker as a replacement. Being that old it is also not optimized for VHF and UHF channels that are in the Seattle area. I am 31 miles from most of the transmitters. A preamp would probably be of no use as I have strong station reception on at least 1 channel.

Answer: Hi Mike,The HD Stacker has a VHF/UHF phasing unit located on the UHF antenna boom very similar to most VHF/UHF antennas including your Radio Shack antenna. The phasing unit couples the VHF and UHF signals together with less than a .5 dB signal loss.
TV antennas are 300 ohm until converted to 75 ohm. The antenna includes a balun that converts the output to 75 ohm coax cable. Even the Winegard HD series antennas are 300 ohm until the snap on balun cartridge is installed onto the antenna.
The Stacker antenna performs better with the VHF antenna on top. If the UHF antenna were on top I really doubt that 18" of increased elevation will make any difference in the reception.  
The Stacker antenna was thoroughly tested and tweaked by the Winegard engineers. It performs as advertised.
I can tell by your questions you have been reading comments posted on forums. Most negative forum comments about the HD Stacker have been posted by our competition and are not from actual users of the HD Stacker.

Comment: Denny, It is important to get all sides of the issue in a discussion in making any logical decision.  Thank you for your quick response and input. Mike

Comment: Mike, I agree. However, it's important to identify the source of the information. Bad information will not lead to a good decision. I have no respect for those competitors who hide behind a forum screen name and post negative comments about any product they have never tried. On the rare occasion I do submit a post to a industry related forum I use my full name and business name so the reader can evaluate the source of the information.
I'm not saying all forum members should identify themselves only those who own or are employed by a business that is related to the forum subject. For an example, If I state a negative comment on a forum about a competitors antenna I should feel obligated to identify myself as the source. If the statement is true why would any business owner or employee of the business choose to remain anonymous?

Question: Hello Denny; We have a problem here in east county San Diego where our UHF channels come from Mt Miguel but the VHF comes off of Mt. Soledad on a 150 degree spread. This is too far apart to split the difference and point between the two. Can one aim the UHF and VHF portions of your HD Stacker antenna in different directions 150 degrees apart? Is some sort of diplexer needed to blend the signals? How far do the UHF and VHF elements need to be spread apart to avoid degradation of the signal? A rotate would be hard to program to change automatically for Tito recordings. Thank you for any answer you can give on this matter, Jim

Answer: Hi Jim, The VHF and UHF antennas of the HD Stacker can be aimed in different directions. We have a page specifically for San Diego reception and how to aim the HUD Stacker antennas in different directions.

See: Best TV antenna for San Diego > 


Question: Hi Denny, I understand that several HD Stacker's can be coupled together and aimed in different directions to eliminate the need for a rotor.We have signals coming from 3 directions I would like to link at least 2 Stacker's together if possible,your thoughts and recommendations on doing this.We have 3 T.V.s and we are located near ST. JOHNS,MICHIGAN.Thanks for any advice you can give, Ron

Answer: Hi Ron, I recommend coupling two HD Stacker's but 3 becomes difficult to do properly. You run into more complicated signal phasing issues when coupling 3 antennas.
The proper method when coupling 2 Stacker's is as follows. Use two coax cables of the same length (4 foot cables work good). Run one 4' cable from each antenna to the CC 7870 mast mounted antenna coupler. Out of the coupler run another short cable to the mast mounted AP 8700 preamplifier. The down lead to the house connects to the output of the AP 8700.
The above set up will properly phase the two antennas and provide the signal amplification needed to supply 3 TVs.

Question I want to install the HD Stacker in my attic. The opening into the attic is 24" x 22". Will the antenna fit through this opening?

Answer Yes, the HD Stacker antenna requires some assembly. You can partially assembly the antenna so it will fit through the attic access hole and finish the assembly once in the attic. See: HD Stacker assembly >.

Question: Hello Denny, I seen the test page comparing antennas on your website. It seems this would be a fair test since all antennas were tested using the same tuner. Did the HUD Stacker really beat all the antennas shown on this page? Thanks much Gregory.

Answer: Hi Gregory, The test results displayed on the best antenna test page > are real. We did exactly as stated on the page and the results were as displayed. On the test page we offer to re-test any antenna as long as the request comes from a legitimate source. This page has been on line for two years and so far no takers on a re-test. Best regards, Denny

Question: I just replaced a Radio Shack antenna that was over 10 feet long with the double HD Stacker. I changed nothing but the antenna. The reception is noticeably better with the HD Stacker. This is especially true on two of my weaker channels. I'm happy as %#*&. My question is how can an antenna that is only 6 feet long work better than one that is over 10 feet?

Answer: I can't take all of the credit for the performance of the Stacker a lot of the credit goes to the Winegard antenna company engineers who tuned and phased the antenna for us. The HD Stacker in reality is about 12 feet long if you place both antennas end to end like other VHF/UHF antenna are designed. I simply had the idea of placing one antenna above the other reducing length and wind load and increasing stability. The HD Stacker design > page explains this best. You may also want to visit the HD Stacker story > page. Take Care, Denny

Question: Interested in using two of your stacked antennas (one facing north and one south) using a combiner and pre-amp. How well would this work? I do not want to use a rotor due to feeding multiple TV's. Thank you in advance. Here's the address of where the antenna will be installed xxxx Dogwood Trail Jupiter Florida 33478. Thanks in advance, Mike

Answer: Hi Mike,
Two coupled HD Stacker antennas > will work great. In fact there are a few customer's in your area doing just that.
Our concern when doing this is to provide enough signal amplification without over driving the signal. The best way to do that is to utilize two amplifiers. I recommend the LNA 200 preamplifier > and the HDA 100 signal distribution amplifier >. In cases like this two lower output amplifiers work much better than one high output amplifier.
The set up goes like this.
With one Stacker antenna aiming North/Northwest and the other aiming South run a short coax cable of the SAME length from each antenna to the CC 7870 antenna coupler >. The 4 foot coax cable > we offer work great for this. From the coupler run another short cable to the input of the LNA 200 preamplifier. The 2.5 foot cable > we offer works good for this.
From the preamplifier output connect the down lead coax cable that runs into the house. In the house run the down lead cable to the input of the preamplifier power inserter included with the preamplifier. From the output of the power inserter run coax cable to the input of the HDA 100 amplifier. From the output of the HDA 100 run cable to the input of the signal splitter and from the signal splitter to the TVs.
This system should work great and provide 24/7 quality reception.
