That, along with perhaps a dozen others dealing with rural settings, were canceled because the network(s) wanted to appeal to a more modern, urban audience. As Pat Buttram (who played Mr. Haney) remarked after the blood dried, "That was the year they axed everything with a tree in it." <paraquote from memory.
Most of these shows can be seen regularly
for free on the OTA (Over-The-Air) channels now (ME TV, Antenna TV, etc.), including Green Acres. (I have seen the old Magnum P.I. offered on one of the OTA channels, too.)
Re Eva Gabor: ✓ As well as a lot of the lovelies on those shows, like the girls of Petticoat Junction, and of course Donna Douglas (Ellie Mae of Beverly Hillbillies), Elinor Donahue (Sheriff Andy's GF)....
And few indelicate words were necessary.Terry, 230RN

I think they just call it a "digital" antenna to encourage you to buy a commercial one. However, commercial "digital" antennas designed for the OTA frequencies involved do work better. I get by with a 6" diameter loop connected directly to the ends of the 75 ohm input cable, no impedance-matching or balancing required. The other advantage to OTA reception is that only another antenna is needed for other TV sets in the house... no "extra" boxes needed.
