I said that because when it comes to major news media outlets that are conservative it's pretty much just Fox.
That's mainly the fault of the conservative audience, though there are a couple of other historical factors in there, too.
The conservative largely audience doesn't want news. They want strident opinion and propaganda.
To illustrate that, here's a shot from the latest Media Bias Chart:

I'm not posting this to discredit any particular outlets or even to criticize them. I know folks use this chart for that purpose, but I don't, because what it really shows is, along the vertical axis, how much a given outlet leans on opinion versus factual reporting. Opinion, in itself, isn't necessarily a bad thing. Or, to be more specific, the top half sort of goes between Facts and Reasonable Opinion, while the bottom half goes between Reasonable Opinion to Nonsense.
(as an aside, I'm surprised to see the Jimmy Dore show on the left. I've never heard the podcast, but I have seen him live and he and his wife were both very Trumpy. I am not surprised at where he's positioned vertically.)
Notice how the left-leaning outlets are distributed vertically vs the right-leaning outlets. It's a little tough to see at this zoom level with all the icons, but there's a high concentration of left-leaning outlets near the top, which is where your traditional newspapers and nightly news shows sit, with lots of fact report along with some in depth analysis and some mostly-not-strident opinions. But on the right, there's a big hole there where the arrow is pointing. You have WSJ, Christianity Today, and a couple of Fox Sunday shows and that's kind of it aside from a few smaller ones like the Dispatch and CT. The right-leaning outlets, especially the more popular ones like Fox News, NY Post, and OAN, are distributed lower on the vertical axis, because they rely more on strident opinions than fact.
Fox News started out trying to be proper "news," but eventually realized that it was more profitable to be a right-wing propaganda machine. Likewise, a lot of those conservative outlets are much younger than the mainstream/left outlets and, as such, developed on platforms where outrage was more profitable. It's hard to start a new tv station or print newspaper and compete with NBC or NYT; heck, it's hard to do original reporting of any sort, but it's fairly cheap and easy to start a website or podcast and load it with opinion.
If the conservative audience wanted reasonable news reporting, you'd have conservative outlets providing it. There's more than enough money to get that done. Rupert Murdoch alone is worth over $19 billion. Trump has another several billion, as do a bunch of his buddies and donors. Robert Mercer, the former CEO of Breitbart, has close to a billion. Limbaugh was probably pushing a billion, too.
