Ancable 75 Ohm to 300 Ohm UHF/VHF/FM Matching Transformer

Works

Conexión perfecta para la televisión

The ends that screw to the antenna posts could be a little longer and stronger, but they did the job well enough.

I own a Marantz ST6003 which has struggled to get FM reception in the area we live in using dipole antennas. I ended up buying an omnidirectional antenna and mounted in our garage attic space a few years ago which helped however I recently noticed almost all my radio signals were struggling, I ended up putting a dipole on to just get basic reception. I was thinking the builtin transformer to the antenna might be the culprit (perhaps the extreme temps in the attic caused a failure) space so I figured for a few bucks it was worth it to see if this would help. Lo and behold, after I installed this, the signal improved ten fold and I feel like I am getting about 4db of improved signal over what I was receiving prior. I am not entirely sure why this added the improvement since I didn't take the original transformer apart but I'll take it.. I will be the first to admit, the antenna in the attic is less than ideal but it beats a dipole antenna hanging off the wall having to be moved around all the time and an outside antenna is a non-starter in our neighborhood.

Used for older tv that does not have coax screw into connection. Used to resurect an old TV to connect a Digital antenna. This is well built, not junk. Will buy again to keep in my repair box

Is what I wanted thank you

The 75 Ohm to 300 Ohm Adapter for UHF/VHF does the job but falls short in terms of quality. While it meets basic needs for connecting antennas, the build feels somewhat flimsy and may not be as durable as higher-end options. It’s functional and gets the job done, but if you’re looking for a more robust and long-lasting solution, you might want to consider investing in a higher-quality adapter.

Needed for tv antenna

This was exactly what we needed to connect a (new to us) old receiver to speakers in the garage.

Attention, connecteur américain à visser. Il faut un adaptateur.

Wie beschrieben. Fürs Geld ein ordentliches Adapterpaar.

If you need to connect a coaxial cable fitting then this is a good way to go. Does it improve reception over and above a wire twisted around screw fitting - no, but I didn't expect it would.

Da la impresión de estar bien construido. Lo utilizo para conectar la señal de antena de FM del edificio (cable coaxial de 75 ohm de impedancia característica) a un receptor de radio con entrada equilibrada de 300 ohm. Funciona bien.Para los más entendidos, he medido la relación de ondas estacionarias aplicando la señal de un generador de RF con salida a 75 ohm y con el dispositivo cargado con una resistencia de 300 ohm. El valor que obtuve, creo recordar que era de 1.2 a 1.3 en la banda de FM (78-108 MHz). Esto implica que refleja entre el 1 y 2% aproximadamente de la energía insertada, lo que está muy bien a efectos prácticos.
