Like rickbb, I use a tuner and computer... my system uses SiliconDust tuners and a Linux OS computer. The recordings are just files... MPEG 1/2 format as they come off the air.
I also have started using a model HDTC-2US (SiliconDust) which has the hardware to transcode to lower bit rates. This makes my tablet a functional TV and with VPN connectivity and adequate bandwidth, I can remote into the tuner via the Internet.
If the well is dry and you don't see rain on the horizon, you'll need to dig the hole deeper. (If the antenna can't get the job done, an amp won't fix it.)
