Bought a new guitar (Gretsch 5220)
New practice space. We had to vacate our old one. An hipster western bar (The Ghost Ranch) is being remodeled and the building's new owner is letting jam there until the crew starts at the end of July.
** Tech Help Request ** New (old) radio day. I found this at a rummage store and grabbed it. It works perfectly but I would like to put an antenna on it. Suggestions? I live in the mountains so I'm not expecting much.
Saw a moose and her calf today.
Took 'ol Iz for a buggy ride to the river a bit later.
I bought some new sneakers, too.
That's it.

I'm suspecting that you probably don't need much reverb coming out of the amp playing in a big empty room like that.

As to the radio, if you have any type of old TV antenna (whether outside or rabbit ears) that used to clip on to your old TV, any other type, you just connect to the RED terminal.
With the exception, if you have a coaxial TV antenna, you can connect a TV balun between it and the radio:
Nice Gretsch.

Nice Gretsch.
WOW a 75 ohm transformer I haven't even thought about one of those in years and I used them everyday. TV's and radios all used to have the 300 ohm connectors which were the two screws in back and coax just didn't work very well without them. I worked for the cable company from about 82 til 94.

Now that was random. Well done.
I remember those 300 ohm things. What were they for? If e everything needed an extra 300 why didnt they just build it in or match the impedance to begin with?

Because coaxial cable =75 ohms. You get less loss on coax over long distances compared to 300 ohm twin lead.
When TV came along the standard for antennas was 300 ohms thanks to FM radios so that was used for TV.
As you alluded, things work better when impedances match so it was easier for cable companies to use 75 ohm coax
and use the balun transformers to match to the TVs of the time. Make sense?

Back in those days I put up antennas on the side living here in the mountains there were a lot of people that could not get cable and cable only offered a few channels and those only on low mid and high band. In fact there were no sat channels for much of that time. I would put up a Channel Master Antenna with a rotor that required pulling 2 flat wires a 300 ohm 2 conductor and a 4 conductor for the rotor I would bring them into the house and used a 20db amp and 2way splitter to hook up 2 TV's for $150 of which I would clear $60 which was a lot of money for a half days work in the 70's and early 80's.
Man I'm old and if your post are as telling as I think they are you must be too

I have heard rumors that Mickey dated Eve before she met Adam.
