Today I decided to connect our home TV for local OTA (Over The Air) digital TV. We had dropped cable some time ago. The old (huge) TV antenna was not providing a signal which turned out to be a bad cable which was not unexpected given its age.
Here is where this is pertinent to our RVs and campers; I have seen threads by people trying to troubleshoot their TV/antenna installations and like them I needed to find out where my issues lay. A quick internet search returned a number of DIY antennas for digital, but I had been informed (by media sources) that digital needed "special" antennas. I decided to try this one because it required very few tools (scissors, knife, pliers):
Pie-tenna, The simplest HDTV antenna possible, possibly. - All
Bottom line, it works great! Taped to the wall behind the TV (6 ft high) it pulled in stations up to 40 miles away and when moved to a higher location in the attic the reception increase out to 60 miles. This is equal to the factory antenna on our Vibe. Of course, reception will depend on the actual presence of stations and signal strength, but for a bit of coax and a pie plate this makes a great testing tool, or permanent replacement antenna.
