I have a RCA Yagi in my attic.

[RCA Yagi Amazon Link] (TVAntenna-RCAOutdoorYagi...https://www.amazon.com/dp/B0024R4B5C?ref=ppx_pop_mob_ap_share)

Currently on a 2-way splitter, but I would like to add a third TV. Could someone recommend the best splitter for a 3-way? Possibly with Amazon link.

I’m confused about MHz range. And best brand. Or if using a 4-way with one unused would work, since there seems to be more 4 than 3-ways.

Thanks!

The highest frequency a TV antenna signal splitter needs to pass these days is 608 MHz, which is a lot lower than it used to be before the FCC frequency repack giving all the upper portion of UHF TV frequencies to the cellular companies.

UHF tv channel 83 was at something like 890 mhz, I think.

but today the highest frequency is uhf channel 36, which tops out at 608 megahertz.

And almost any splitter of any age will pass frequencies well BEYOND that, so this is not at all critical UNLESS you have a very WEAK signal situation to start with ...AND then probably only if you manage to find a splitter that actually attenuates signals significantly beyond 600 MHz, which probably isn't very likely.

Just keep it SIMPLE and try a low-cost under $5 4-way or 3-way splitter.

I'm guessing it will probably work just fine in your situation, unless again, you're in a very weak signal situation where you need every bit of signal possible.

Here's a 3-way Splitter from Amazon that should work for you, but at $7 it's about twice the price it should be, but that's typical for Amazon prices for most everything:

A local Walmart store might be a good place to look for splitters. Also places like Home Depot or Lowe's or even some dollar stores.

And fwiw, get a rabbitears.info report for some good additional info for your particular signal situation. If all or most of your signals are rated as GOOD on that report you should have no problems at all.
