    Best anteanna splitter

    The better place to install the UHF splitter is after the power supply, not between the power supply and the preamp. This negates the need to splice the line that carries the aproximately 20 volts that powers the preamp. With your situation you should have plenty of signal to power the 2nd tuner.

    stacked two CM-4228 vertically

    I think that unless you have a very long coax downlead (200 feet or more) and have a lots of tvs running or lots of loss before the receiver (multiple vcr's hooked up) the gain of the 7777 is plenty. The real improvement can be had with careful selection of the matching transformers and the 2...

    cable lenght from receiver to tv?

    Oops 3db/hundred is the loss at channel 13, it's only 1.5 db/hundred at channel 3 meaning bareback without an amp should work fine at 500 feet hooked directly to his TV.

    cable lenght from receiver to tv?

    I'm thinking the output will be at channel 3 or 4. With RG6 having a loss of 3 db/100 feet at those channels a low cost amplifier will be able to overcome the 500 foot loss. Even with no amplifier you should be able to supply a slightly snowy picture after 500 feet of RG6 depending on the launch...

    How to hook up two Silver Sensors

    You should be able to hook up two Silver Sensors by using a 75 ohm two set splitter that is rated to 800 Mhz or more. This is the common type of splitter used by cable companies to feed two tvs from 1 coax. In theory you'll have a better chance of success if the two antennas are pointed 90...

    HD-OTA antenna placement

    You might try a couple of temporary attic locations for best signals. I drill a hole in an inch and a quarter antenna mast and hang it from a high point in the attic. All you have to do is use a single nail to hold the pole and use your signal strength readings to choose the best location...

    OTA Antenna Troubleshoot

    This looks alot like a Winegard CS 7082. It's UHF and VHF and I can't see any missing elements but on the bottom side there should be a blue clear plastic box that has a circuit board inside. There's a couple of common misinstalation problems associated with the circuit board. Make sure at the...

    Coax rating for in-wall install?

    From my commercial instalations the only time that higher rated cable is required is if the space that the cable is running in is also an air chamber. What I mean is if your air handling system uses the above the ceiling area to draw air from you need a fire rated cable. This is usually called...

    How to amplify signal?

    That's not what you want. It's not made for analog chnl 3 signal really but for the signal between the dish and the receiver. For one thing the chnl 3 or 4 output of the receiver does not have the voltage present that is needed to provide power to this amp. You want a 110 volt powered amp...

    How to amplify signal?

    You can buy the 20 db gain model but it probably won't improve the signal quality at your remote locations that are only 50 cable feet away. It does give you some extra sig if for instance at your remote locations you also have a VCR in line before the sat sig reaches the tv. VCRs can have 5 or...

    Does anything tend to dx as a signal?

    VHF channels 2-6 can sometimes travel great distances when special climate conditions affect the upper layers of our atmosphere. You usually see this in the late afternoon and early evening in the hot summer months. I.ve seen maybe 7 states and 3 Canadian provinces when I lived in the high...

    How to amplify signal?

    Something I left out of my DbMv calculations that some may not be aware of is that a very good tv signal level to have at your tv is +3 DbMv. Levels above +3 won't look any better than the +3 DbMv level.

    How to amplify signal?

    Your V647 looks to be a +10 DbMv or less modulator. You probably will be feeding a 6 or 8 way splitter which have a 9 or 10 loss. Drop cable (RG59 or RG6 typ)e has less than 1 db of loss in 50 feet. If you add the losses you have about 10 db in loss. Using one of the 10 db amplifiers means that...

    Fittings tight or loose on LNBS?

    I think all connections should be tool tight if the female socket is mounted on a metal chassis. This leaves out tv sets and most consumer equipment. In all cases the person doing the tightening should keep an eye on the female port that your are tightening a male connector to. If the chassis...

    How to amplify signal?

    I agree with rcbridge. The pictured modulator is the same as the one I referred to. They commonly have 10 db gain. If your 75 ohm switch is near the video input port of your modulator and there is also a video out port on the modulator the switch is probably used to either terminate the...

    OTA HD signals

    I think the signal meter measures the quantity of the signal not necesarilly the quality. It's possible the signal has reflections (ghosts). You might go to http://antennaweb.org/aw/welcome.aspx ...and find an analog signal from the same toweras your iffy sig and see if it has ghosts.

    How to amplify signal?

    It sounds to me that you are distributing the rf- possibly ch 3 or ch 4 to the other outlets in the house. If you have multiple cables at each outlet possibly you have a return cable that goes back to a common point (or the common point might be right at your main tv location) where it is split...

    Distant OTA

    I think increased height will give you the most improvement. I don't think you have much chance of success down low no matter what you do. I wouldn't bother getting a second antenna and combining it with your original antenna. Combiners (splitters) at UHF eat up some of the theoretical 3 db gain...

    Diplexing OTA channels to a Dish 921

    If you can pull it off don't use the diplexers but run a dedicated wire frim the OTA to the OTA input on your receiver. There's a huge amount of OTA loss in two diplexers. Only about one eighth of the OTA signal will reach your TV, the other seven-eights will be lost in the diplexers. Close in...

    Distant OTA

    I looked at your RS antenna and it's a medium gain UHF yagi. You first need to get good analog reception from the same tower(s) where your digital transmitters are. If the analog reception from the analogs are snowy you won't be happy with the digital reception from those same towers. I've...

    Chain saw food and LOS

    Remember this is sun outage season so you can use the sun's position in figuring out how much you need to lop off the trees. During sun outage days your BUD needs to have the unobstructed early mornig sun shining on it to get those low in the East birds.

    what angle does signal come in from sky to the dish?

    Since it's very near sun outage time when the sun lines up behind all satellites you can use the sun to tell if you have a clear line of sight to the satellites. The first couple of days in October I believe will be the most accurate for this test. If you can see the sun above the trees in the...

    Can you put an antenna on any metal pole?

    That will work fine with an OTA antenna. Radio Shack sells various offset brackets that will allow you to mount to the facia board even when your shingles stick over the facia by inches. I'd use both brackets on the facia spaced as far apart as possible for increased strength. I usually use an...
