I wonder what the OTA reception is like with digital.

In general, if you had a fairly decent picture with analog, you'd get a perfect picture with digital.  If your picture was more snow than picture (you had to defocus a bit to make out the image) then you wouldn't have digital reception.  UHF is a bit worse than VHF for long-distance, but not dramatically so until you get past the radio horizon (about 60 miles over flat terrain.)  Reception over 75 miles is possible with a quality antenna and above-average terrain.

Would the Leaf brand be OK or an outdoor type. I could move my RCA type indoor aerial to outside to see if that would help.

Indoor antennas are not weather sealed and will corrode/degrade rapidly if left outdoors.  But for a short-term test, it's worth trying.

Could protect the aerial with a plastic bag so that will not happen.

Rain is not the only thing that attacks plastics and metals. UV also rots rubber and plastic (including many plastic bags).

There's nothing "magic" about the Leaf antenna. Just use an outdoor version of a one-bay or two-bay "bowtie" antenna, which is designed to go outside.

They are equal.

Daytime reception is the hardest, when the sun is highest. 

 

 

Even using either the leaf or an outdoor aerial?

There's a lot more junk in the airwaves too.  Business radio like service trucks and cabs, more cell phone traffic, more aircraft flying so more radio traffic to/from them, train communications, traffic light control signals, data to/from emergency vehicles increases, businesses uploading data to satellites (ever see the dishes on top of stores like Dollar General?), etc.

HD, SchmacHD!! Just be glad you've got a picture at all.

I thought those dishes were for some sort of TV reception. The cost between the Leaf and a regular outdoor aerial is about the same.

Do not know which would be better.

I shortened the coaxial cable on my aerial today by several feet. I will see of that makes a difference.
