Best antenna i’ve used, hands down, no powered or amplified, outdoor safe, but I actually have just hung in the the window between the curtains and blinds works great, there are ones out there that have 2 and 4 times this antenna, but even in the south end of lakeville, and not very good line of sight, works awesome.

There are more expensive versions but I can’t see what if anything they are better at. I’d venture the guess a single would be fine, I’m not an expert but it may be possible to have too much antenna, but even so if you bought a 2 or 4 panel one I bet you could unhook them just as easy if you had issues.
Money wasn’t really a concern (within reason) when I bought this antenna, I’ve paid a lot more in the past, this is the best I’ve used.
