Two-way CATV Amplifier, Nihon Antenna SRB-2215, Junk Item
Product Details
This is a used bidirectional CATV amplifier, model SRB-2215, from Nippon Antenna.
This device was used on a coaxial cable television line.
I am listing it for sale because I switched my CATV line from coaxial to fiber optic in December 2025 and no longer need it.
