This post will be a bit long-winded, but I think it all needs to be given for background.

My outdoor antenna system which is at about 25ft at present and installed with all PerfectVision 3Ghz swept RG-6 quad-shield & Thomas & Betts snap n seal connectors, consists of an AntennaCraft Y10-7-13 for my local RF 12 channel. That goes into an MCM Electronics FM filter, then into the non-power passing side of a UVSJ. Then a HDB91x UHF antenna for all my local UHF, went into the 2015 model Kitztech KT-200-Coax preamp, and into the power passing side of the UVSJ. Then, the output of that goes down to the power injector.

After the power injector, I also had a PCT-MA2-4P 4-way powered splitter, though likely overkill, it was there from a previous setup. Off that, I have a Tivo Roamio used for OTA, and 2 tv sets (previously had 3 tv's, but one fried a few months ago).

My house is located at a place where all my DMA's tv towers are in an arc, from North, North-East to slightly West of South. They are also grouped all from around 32 to 52~ miles away. Luckily enough, the highest powered ones are on opposite ends of that arc, and the ONE low power station I want to receive (10KW at 32 miles) is close to dead-center of that arc.

So, my HDB91x UHF antenna is pointed right at that station (WFFC-LD, RF17), and it receives all the other UHF stations acceptably within limits of its beamwidth/sidelobes.

Once I got everything all tweaked and locked down some years ago and finally settled on the KT-200 preamp as being the BEST in my situation out of many that I had tried, I still always felt that there might possibly be more to be gained, and who of us doesn't like to keep playing with antenna setups, lol.

Anyway, I started reading about Televes and their various products this past Winter, and wanted to try one. I finally was able to pre-order a Televes 560483 two-input preamp from Ness Electronics, and got it 3 weeks later. Unfortunately, that was just before Christmas, and Michigan got pounded with too many snow storms to allow me to install it right away, since I had to go on the roof. That's not easy when there's at least two feet of icy snow up there.

I finally was able to install it in February. I eventually did a simple straight-swap of removing the KT-200, and installing the 560483 in its place, along with their power inserter to replace the Kitztech one. I tried various combinations between the antennas/preamp/uvsj while checking it, but NEVER found one that worked even as well as OR better than the KT-200.

In fact, the Televes preamp couldn't even lock WFFC-LD RF17 that the Kitztech could. Locking that station that's only 10KW and 32 miles away, is my gold-standard on MUST HAVES.

Anyway, I thought "Well, that's yet another $70 down the drain, and time wasted trying to beat the Kitztech". I then put the KT-200 back in, and put the Televes preamp into my parts drawer.

That's where it all stood, until a week or so ago after a persons post in the TV and Fm DXing group on Facebook comparing various companies preamps, and I made a reply comment that I also hadn't had any luck with the particular Televes preamp I tried. Javier Ruano of Televes read that comment, mentioned that he didn't think that particular preamp was the best choice for my setup, and offered to swap it out straight-up for the 560383 single input one. I took him up on that offer since I had nothing to lose any way by doing so.

I received a Televes 560383 single input preamp this week Tuesday, and was finally able to install it today in my system, since we've had some bad weather the last few days. I once again did a straight swap for the KT-200, so the preamp is only in the UHF chain. I also of course swapped out the power injector, but initially left everything else the same.

The Tivo Roamio hidden diagnostics screen (which has a LOT of data), showed that Signal strength and SNR on this straight swapout was on average a tad better than the KT-200, but not by much. Since the Televes power injector has TWO outputs and the Televes preamp has a little more juice than the KT-200, I then also decided to remove the PCT powered splitter from the signal chain. I put the Tivo on the injectors main output (since it's my most-watched device) and used a PCT passive two-way splitter on the other output for the two tv sets.

Now, with the Televes preamp, signal strength and SNR readings on average on the Tivo and tv sets are around 4-5 points UP higher than they were with the KT-200, and they appear to be more stable. Also, we are having 30+MPH wind gusts all through this testing today 4/30, and I have lots of trees flapping their leaves starting about 100 to 300 feet away that I have to aim through. Even so, I'm NOT getting any RS Uncorrected errors on my weakest channel, which I was getting a few now and again with the KT-200.

Anyway, I feel that the Televes model 560383 preamp seems to beat the Kitztech KT-200-Coax by a bit, is better built, and I have every intention of keeping it installed. It appears to be built well, has FM & 5G LTE filtering built-in, and I don't think anybody could go wrong in trying them out for themselves.
