Advertisements Recently upgraded to Bolt (4 tuners, OTA compatible) from Premier (Series4, 2 tuners, OTA compatible). No cable. Antenna, splitter, and all coax remains the same. On Premier, I received 100+ channels from my balcony-installed antenna (Clearstream 2V) after going thru a single splitter. Signal strength 60-85+ which displayed pretty well for everyday use. On Bolt, I now receive only about 10-15 channels after the initial channel scan. Signal strength 32 (channels I manually added) or 50. Only the 50+ shows picture). Have combed thru the threads without finding a definitive answer (as well as called Tivo support) to learn what type of amplifier (preamp) / alternate accessory I can install so that Bolt will equal/exceed the Premier performance I grew to love? Moving/upgrading antenna is a long shot (condo HOA restrictions make it very difficult). Otherwise the Bolt will be returned for 30-day refund. Any amplifier recommendations? I'm a reasonably competent engineer but I don't have any signal analysis tools on hand (outside of the Tivo box analytics). Thanks in advance!
