TV Antenna Preamp - how it can help your Television Antenna Signal 

Just bought a Televes dual antenna input preamp and my reception has never been better.

Another great video that goes to Great Lengths to explain exactly what a preamp can do for you and what it can't!

I have been using a Winegard LNA-200 Boost XT HDTV Preamplifier, TV Antenna Amplifier Signal Booster for about 7+ years now. The antenna on my roof is difficult to access, so I use the booster near the TV. Helps with a low-vhf channel (ch6) that otherwise is unwatchable most times. Ran about $40-50.

One of the things that I feel should be stressed is keeping coax as straight as possible and don't make any sharp bends or kinks. I am old school I still use Antenna Mast Standoff rather then tape to prevent any induction from the mast pole and never run RG 6 parallel to AC power.

Preamps can seem to magically get stations/channels that had no picture before because, after scanning, tuners store the data for stations/channels even though some signals are below the threshold to get a picture. You should also tell users to rescan after installing a preamp. From my (and one of my client's) experience, the GE preamp is a good low cost preamp. However, some of the highly experienced senior professional TV antenna installers in the FaceBook group probably have opinions about the noise level of the RCA and the GE compared to the gold standard/best/unique (and probably highest cost) Televés preamplifier models.

I have this model it stopped working after a few years luckily I had a extra one do thay still make this model if so where can I buy one.

The antenna with preamps are suitable for places with medium to low or low signal. The good part is that you can use a classic splitter mounted after the inserter. Do not mount a splitter between the preamp and power inserter becuase you either have no signal or the signal is bad especially on UHF band. A classic splitter has between 4 - 10 Db attenuation, a diplexer has 2 Db attenuation. I rememeber one case where I had to install a UHF Yagi antenna with 44 elements with a built in preamp. And in order to connect to multiple TVs I also had to install a 20Db amplified splitter to have the signal strength between 80 and 90%. to connect to 3 TVs. The reason was the tower was more than 50 km away and lots of trees. No possiblity to install a satellite dish, otherwise it would have been much easier. The best part is that the preamp can be easily replaced. If you don't need the preamp you can mount an impedance adapter or matching transformer and use it as a regular antenna. Preamps can help you with DX-ing if you want to receive channels outside your area but you need an antenna with higher gain.

I’ve got a Channel Master 8 bay antenna on the roof with a 10 ft mast, and pre-amp mounted on the mast below the antenna. When it was installed, instead of running the coax straight from the antenna signal box down about 3 ft to where he mounted the pre-amp, he ran the coax up to the top of the mast, down the inside of the mast, and then back up to the pre-amp, adding about 10 feet to the length of the coax between the signal box and the pre-amp. Do you think I’d lose channels less often if the coax was run directly down the 3 ft from the antenna signal box to the pre-amp?

But the preamp will slso amplify the noise right? Will it maybe produce any extra noise on some part of the rf spectrum? Also do these things have any filters in them? I would like to use one of theese for SW band not tv, and I dont want it to filter any frequencies Also what happens if u feed the signal into it, will it pass the signal back to the antena I sometimes like to use my antena to transmitt signal so I connect a transmitter to its input and because its directional the signal can be received far away So if I put preamp in between will I still be able to do this or the amplifier block the signal?

Just to add, it's probably a good idea to weatherproof your outdoor coaxial cable connectors even if you don’t purchase an outdoor mounted preamp. RF Weatherproof Boots are incredibly easy to install as they simply slide up and over the connection. They slide back off of the connection just as easily, making them a great coax connector weatherproofing solution, especially when you are concerned about re-accessibility to the connection. There are different types of boots to match different connector and cable combinations, You can also purchase one that is IP68 rated should you choose to do so.

What do you think about using a preamplifier and a distribution amplifier? Is it a good idea? Or is it overkill?

If it runs thru your 'tv box',it ruins everything. Better connect the co aux cable to your tv set directly.

IMO this one is junk, get a Maspro for about $30-40. Every connection is about -2db plus each split is -3.5db so it adds up. Usually you'll be good with a quality 20db amp.
