why does Blonder-Tongue offer two new indoor boosters?
Let's talk straight-from-the-shoulder about indoor boosters. Transistor boosters provide higher gain and are more rugged, but they have one problem — overload (windshield wiper effect, loss of sync, etc.). If you use a transistor booster in an area with one or more strong TV or FM signals — you may be buying too much booster! On the other hand, tubed boosters perform very well in these areas — and what's more, they cost less.
