Repurpose Antenna?

[forbiddenera]

I could potentially use this antenna for stuff but I'm not sure exactly what.

Pretty sure it's an old TV antenna, so the highest frequencies it'd really be good with is maybe uhf, so maybe HaLoW could work, maybe. Of course I'd want to make sure I'm within any legal limits. 2.4ghz would be sick but from what I've read since this antenna isn't really tuned for that it's probably not going to work or work well.

No idea if there's anything between the antenna and the coax port inside. Of course there's the whole impedance issue as well depending on what I use it for.

Sorry I'm pretty noob with rf but want to change that. Also have a reflector dish but it has nothing on it, maybe one day I'll figure out how to strap some antenna and a motor to it and listen to some sat stuff

Looks like a stacked pair for maybe TV ch 2, 3 or 4 and only good for one channel. It’s hard to judge the size and I don’t think it’s an FM broadcast antenna as it would typically be a log periodic and not a Yagi for something that size. It’s not really good for anything except what it’s built for or maybe scrap aluminum.

Are you wanting to use it as is? Or are you willing (or able) to get up there and adjust the lengths of the elements?
My personal opinion, As is it should be better than using just an inside antenna for anything you may want to listen to.
Go ahead and hook it up. Now like I said it would be sweet if you were able to tune the elements to what you like to monitor the most.

I had some limited results using an old TV antenna in the attic as a scanner antenna. I used 75 ohm coax and fed it to the antenna with a 300-75ohm balun.

However, the antenna was horizontally polarized and most signals monitored on a scanner will be vertically polarized. It's also directional, which is an issue if you want to receive signals from multiple directions. You would need a rotator to aim the antenna.

Honestly, I would just buy a purpose-built scanner antenna and re-use the mast/mount.
