Yes, two amps work fine. The absolute best VHF antennas are separate units. One just for VHF low, and the other for VHF high. There is a huge gap between channel 6 and channel 7 - although the numbers make it sound like just one sequential step. That huge gap inbetween 6 and 7 is where FM radio is. Channels 2 - 6 use a low-band VHF antenna. Winegard YA-6260 for $50 or Antenna Craft YA-1026 (hard to find). Channels 7-13 use a high-band VHF antenna. One of the best is the Antenna Craft Y10-7-13. $40 or a Winegard YA-1713 for $48. You can join them with a $3 low-VHF/high-VHF coupler. You can also buy another $3 coupler that will join that to a UHF antenna so you can use all three with just one amp and coax. You can also buy a combo low-high VHF antenna that can do near as well. The best ever made was the Wade VIP 307 (very hard to find). And you can also buy a combo antenna with low VHF, high VHF and all the UHF combined. Winegard HD8200 is the best on the market. Channel Master Crossfire is near the same. These are their advertised gain-specs per channel. Winegard HD8200- Gain: Chan/dB, 2 - 7 dB, 4 - 7.7 dB, 6 - 6.4, 7 - 10.4, 9 - 12.6, 11-11 dB, 13-12, 14 - 14.2 dB, 32 - 13.7, 50 - 12.2 dB, and 69 - 13 dB. Channel Master Crossfire 3671 - Chan/dB, 2 - 4.9 dB, 4 - 5 dB, 6 - 6.2, 7 - 11, 9 - 11, 11-10.9 dB, 13-9.6, 14 - 7.5 dB, 32 - 9.8, 50 - 12.5 dB If you don't want to mess with three different antennas get the three TV bands, you're better off just buying something like the Winegard HD8200. Has all three combined and does a pretty good job on all channels. It's big though. It measures 33" X 110" X 168.25" Has 34 VHF and 34 UHF elements.
