Combining two TV antennas for better HDTV reception
What do you do when you want to receive OTA (over-the-air) HDTV signals from two different directions but your setup makes a rotator impractical? This video describes combining two antennas into one feedline to solve this problem, and also explains the problems people sometimes face when trying to receive OTA broadcasts.

This is a mini-review and mini-HOWTO for the $75 UT5JCW 2m VHF transverter when used with the Flexradio 6000 series radios. It should be applicable to the Flex-6300, Flex-6500, and Flex-6700 transceivers. These transverters are available at transverters-store.com I have no association with this company other than as a customer. Note: I incorrectly refer to this as a Russian-made transverter. I ...

    Cheers. This did help. Thank you. Cable is definitely out. Everyone is foregoing it. Usually, the powered indoor antenna you buy at Walmart; which is what we did. It is more common sense. Yes, we're not getting the plethora of channels we did before and didn't watch anyway. The first month of not getting a cable bill makes up for it. We have our home back and there isn't this monster in the living room that we can't stand and have to financially support.

    You can eliminate multi path distortion from two antennas if the distortion is a result of both antennas picking up the same signal. A Televes SmartCom will filter the duplicate signals by blocking the channel frequency on one of the antennas. It automatically blocks the lower dB duplicate signal. It won’t however separate two signals from two markets that are the same frequency. Usually that isn’t a problem though as the FCC keeps neighboring cities on different frequencies. It’s about the same price as a quality rotator but without the hassle of rescanning.

    I hope you can answer my questions on this. I have a high gain antenna focused on Boston MA from my location. 45* to 50* to the west is Providence, another 3 channels that way that barely come in. Would there be a issue with that as it's off in roughly the same direction? I would also be using a different type of antenna.

  • @stevejohnson1321
    @stevejohnson1321 Рік тому

    This works largely thanks to error-correction buried within ATSC1. Back in the analog days there probably would have been some ghosting and cross-talk. I pick up two opposing markets with a backless channel master 4221. Without error-correction the shield would have been essential. We mainly got ghosts back in 2008.

    okay, newbie at this here - connected a Winegard flat amplified indoor antenna, 5L5500A to my bedroom Vizio smart tv. I get some stations really well. This antenna is in a 2nd story window facing North. I see a lot of stations are south of me - I was thinking of adding a flat antenna also to my dining room window, facing south. So I would want to combine the south antenna near my two tv's, and branch off to them - then on my north facing tv, I would want to combine that antenna to go to both tv's - so it seems as if I would have to combine the south antenna cable into 2 cables to go to each tv, in 2 separate rooms - then on the north antenna it sounds as if I would have to combine that cable to go to each tv - then I would have to combine the 2 cables at each tv into one to hook up to each tv? What type of splitters would I use, I assume powered ones - and what quality of cable would I use for a fairly long run like this - my place is a 2 room condo basically, with other small rooms as offshoots.

    I watched this great video again. Our local VHF TV station finally moved to UHF this past year and I can finally take down those big antennas and replace them with smaller UHF antennas. How would you recommend stacking two antennas for more gain? I get the identical length cables for that as well, but wonder about antenna spacing? I already use a CM7777 amplifier that gets me a 40-50 signal strength (TV setup). My stations are low VHF and VHF. Great video, simple fix!

  • @dennisjones8991
    @dennisjones8991 Рік тому

    The best way is to use 300 Ohm twin lead to connect the antennas together, then use a balun on the lowest antenna to bring the signal into the house. By using a splitter in the house you can use the antenna "system" to also receive FM radio and hook a scanner to it as well. Due to the characteristics of twin lead, it has LESS pickup of noise AND length between antennas is NOT critical!

    I have a 25’ pole and I’m thinking about installing either 2-3 antennas: I have 56-60 channels with 1 antenna pointing in one direction and about 30 to another. I live about 5 miles from Tijuana Mexico and would like to get more LA Channels and Mexican TV stations. Would adding a 3-Way splitter plus grounding increase my TV’s reception?

  • @Not-Only-Reaper-Tutorials
    @Not-Only-Reaper-Tutorials 2 роки тому

    06:31 this is the way it was done also in the old Analogue systems, although in very simple ones. In a multi-flat buildings, there was an active mixer to combine antennas, and you could receive stations emitting from different directions.

  • @Jack_Savalas
    @Jack_Savalas 2 роки тому

    So your saying connect both antennas to a splitter in reverse so that would go into the two output sides and can you actually run that input side coaxial to another splitter inside the house to split to at least two TV's ?

    • @doughall1415
      @doughall1415 2 роки тому

      Yes you can, but you'll lose some signal in the splitter so a preamplifier can be helpful.

  • @kensmith5694
    @kensmith5694 2 роки тому

    It also can be useful to use a tuner with a "signal meter" function to fine tune the direction of each antenna. There can be funny interactions with objects that refract the TV signal by several degrees. Fine tuning the direction can get you a signal that is otherwise marginal.

  • @TheOmengod
    @TheOmengod 2 роки тому

    So does it actually make the overall signal stronger having the two antennas?

    • @doughall1415
      @doughall1415 2 роки тому

      No, the 2nd antenna (if aimed correctly) just improves the signal from the station in that direction. Doesn't do anything for the stations in the other direction.

    In Europe we have different models of combiners. All combiners have VHF and UHF inputs.. The advantage is that all TV channels are on UHF band, VHF High Band is for digital radio DAB+ and FM analog radio. If you want to combine two TV antennas, you can use a combiner with two UHF inputs, and VHF input has the frequency range 87 - 230 MHz meaning that you get both FM and DAB+ radio. Another advantage is that in Europe most channels are broadcasted from one tower. Let's say you have 20 channels you only need one UHF antenna and with that antenna you get those 20 channel. The interesting part is when you live near the border. You need two UHF antennas, one antenna for the TV channels from your country and the second antenna two receive TV channels from the neighbor country. Also these combiners allow un UHF input power pass if you have an antenna with a built in amplifier, the maximum voltage is 12 volts. Some combiners also have for VHF power pass if you use and FM-DAB+ antenna with buit in amplifier. The bonus part is these UHF combiner have 4G LTE filter so phone signals don't affect reception

      No, it's already grounded by being planted into the ground... you can still use it even if it's 50 years old... currently renting a place that has one as you describe, I'm using it and it's feeding me free TV channels from Buffalo to Sarnia (from, to)

  • @Rondogardener

    I installed an outdoor antenna about a month ago to "cut the cable." Then, we started having pixelation. I have a line-of-sight view for about a mile toward Shreveport before the distant small hill. The tower distance is 55 miles or less. That put our dropping Dish on hold. Then the other day, every channel went blank. I contacted the KTBS engineer, and he assured me that nothing was wrong at their end. Then, unexpectedly every channel began to come back. It was weird. I was wondering if all of the UHF channels in Shreveport (over 20) were using the same tower support to save money, but I have not been able to find out. Everything seems to be much better now except for occasional pixelation on KTBS. Could I stack two antennas on the same pole about 6 feet apart and possibly improve the signal by combining them with a splitter? I do not want to drop Dish if this might not solve the problem. The antenna I purchased cost less than $30.00, and purchasing another would not be an insurmountable cost.

  • @kalijasin
    @kalijasin 2 роки тому

    Back in the day it was called diplexer. They were very common for use in satellite installations in the 90s. Directv and Dish didn't provide the local channels back then so you needed to have a TV antenna. The "diplexer" was a combiner too it just worked over a broader range of frequencies. The KU band Directv and Dish use is 12-40 Ghz. Whereas regular OTA broadcast NTSC/QAM is 52-698MHz (ch. 2-51).

    Thankyou. In the UK we still use both TV Ariel (antenna) and cable. We pay the BBC a licence fee and pay for cable. I think you have given me the answer I’m looking for. I live in Hartlepool, England. My signal comes from the Bilsdale Transmitter Mast in North Yorkshire which burnt down last year cutting off millions of viewers. After arguments with the landowner they put up a temporarily mast half the height. They also put a second temporary mast nearer but in a different direction. I have two tv Attentas one I can’t get to on top of my chimney towards Bilsdale and one in the attic for different tv’s in the house. I have ordered a signal finder from eBay and will experiment with joining the cables. Cheers
