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.

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...

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.

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...

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...

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...

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...

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...

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...

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...

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...

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.

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...

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...

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...
