Televes 1-Input TForce Mast Amplifier with BOSS-Tech and “F” Power Supply Unit

Had a few channels with picture strength at around 24 and quality at around 30. Picture would often break up. Now the picture strength and quality is now 100% with all the channels.This deserves a 5 star rating for now and I'll update this review if any problems arise . Assume for now that all is good, posted Aug 2024.

This is a terrific preamplifier for Over The Air (OTA) TV antennas.The YouTube channel Antenna Man has a great video review of the dual input version of this antenna - you can find it by searching his channel for "Televes preamplifier".Televes is a major Spanish manufacturer of TV equipment, including antennas.I only needed this single input version because I am fortunate in that all the TV stations in my city come from one direction only - if you live in a place where the major TV signals come from two directions, then the two input version is for you.At 2:21 of Antenna Man's video review, he shows the frequency response of this preamplifier - this device has three band pass filters that only pass through the low VHF (channels 2-6), high VHF (channels 7-13) and the UHF (channels 14-69) spectrums of OTA TV.This is what gets filtered out as a result:Below channel 2 are the military and government low band VHF channels (30-50 MHz) as well as CB radio (still used by truckers today)Between channels 6 and 7 lie a variety of channels - FM radio, ham radio, marine radio, and more military radio channels.Between channels 13 and 14 (the high band VHF and UHF) lies a huge band reserved for military and other government (including the FAA) usage.Above Channel 69 lie all the cellular phone spectrums.So, instead of just an FM filter or LTE/5g filters, this Televes preamp filters out EVERYTHING that you don't want in an OTA TV signal by using these three band pass filters that ONLY allows the signal that you want to get through.The other great thing that this preamp has is an automatic gain control that adjusts for the strength of each frequency band - this prevents one strong signal from swamping out the amplification of weaker signals.The combination of this sharp band filtering and automatic gain control is that all the electronic noise that exists in today's highly mobile environment does not get amplified into the frequency you want and obliterate it.I had a Winegard preamp on my TV antenna, and we were unable to consistently get channel 2, and there was no channel 3. At a previous house in another city, I had used both a Winegard and then the GE preamp, and both would routinely lose Channels 8 and 10.With this Televes preamplifier, I now get Channels 2 and channel 3. From 93 channels, we now get 118 channels.Installation proved to be fairly simple, although the instruction sheet is almost unreadable, with a microscopic print and use of symbols and non-intuitive language (those Europeans love symbols!).I spent some time trying to figure out what the "DC out" on-off switch was for. So, to save you some time, what I discovered was that Televes has an active antenna using what they call BOSS-Tech, which requires further pass through of this DC current. This preamp comes with this on-off switch in the "off" position, which is what it should be left at if you are using just a normal antenna (turn to "on" only if you are using a BOSS-Tech active antenna).So, for installation, just like every other preamp, there is one plug that goes to the antenna and one that goes to your house/TV line. The single input preamp has two additional screw thread outlets that are helpfully already plugged up as they are not in use (they are for the dual-input version).At the power adapter side, same thing - one plug connects to the incoming line from the antenna, and one goes to your house/TV lines.The power adapter has an auxiliary plug which you can connect directly to a TV or another house/TV set up if you want, but I connected the main outlet to a 9 Port Bi-Directional Cable TV Splitter Signal Booster/Amplifier (as listed on Amazon) to distribute to the rest of the house wired cable system.As for the other reviewer's complaint about the screw threads being easy to cross thread - yes, I can see if you are in a hurry, and aren't careful, but just make sure you have the screw ends lined up properly, and I always turn the threads in reverse first to line things up.I used an RCA ANT751E antenna for this setup and put it in the attic with a 50 foot quad shielded solid copper core cable, as recommended by Antenna Man.

It was worth the money, easy to setup, gave me a strong signal with a crystal clear picture.

This is the best preamp we've used.I still have the LNA 200, it works good and I keep it as a spear. Antenna Direct Juice works as good as the LNA 200, but since it didn't make any difference to reception was returned. Televes 560383 improved picture quality and now we have more channels.

Easy to install. Comes with power supply. Improved my SNR about 8dB (22 to 30) from previous RCA amp.
