Tom Bombadil said:And how long of a lifespan would my old legacy gear be expected to have? Some of it is now 8 years old. It continues to work fine.
Possibly, for 30 years plus. Some old satellites more than 30 years old in the harsh environment of space, still function. It's dust on the solar cells, dying batteries, corroded connections, lack of fuel, and problems with mechanical actuators that usually cause satellites to die.
I install a lot of the latest technology switches and lnb's.
But, for me, I have a legacy quad on a Dish1000, with a single lnb on the 129 mount cascaded via an sw21 for my new 211. My other receivers are a 522 and an old 2800 hooked to a stand alone TiVo.
