Im not able to drill a hole in my bedroom wall for me to run coax to my yagi outside . Can the terra wave 800 mix yagi receive signal inside ? . I'm guessing not but wanted to ask . have an open attic but still don't want to drill a hole .
Receiving inside brick home .

is there a window in the bedroom? A 1x3 board, with holes drilled in it for running cable is placed at the bottom of the window frame...the window it c;losed tight on it and then one of those window locks on the side is installed to keep the window down and secure(one on each side if you want)...pass the cable thru the board and the attach the proper connector and pull it on to the radio. Drill more than one hole, for expanding the antenna array!
Sure it will receive inside, but not as well as outside. Attics are often a problem, depending on wires, foil backed insulation and whatever else lurks up there!!!
Here's a commercial version of this idea....only it uses connectors thru the panel....you may choose what works for you...

yes antennas do and will work inside your home somewhat, but you will be much better off using the antenna outside. i used a bunch of indoor antennas when i lived in an apartment complex with very good results.

I have an older RS antenna mounted on two fence rails the peeks just above our roof. I cut a notch at the bottom of the screen and the bottom of the window (in my case in the lower right corner) and then ran the coax with a bnc connector. It works fine. You might want to figure out a way to protect the coax maybe heat shrink or if you have a short orange extention cord cut off 3-4 inches and push the coax through. This will protect everything.
Hope this helps. God bless

Drill through a mortar joint, not the brick. Easier to drill through than brick...the brick face could become damaged if you are not careful. Also, If you ever remove the coax, it is easier to restore a mortar joint that to fix a hole in the brick.

If you can't drill a hole, you can't drill a hole. Sometimes you just have to work with what you have.
It will depend on how much signal there is to work with. All building materials have some amount of RF loss. You will lose some signal passing through the bricks. If there is reinforcing rod, that'll add to it. If there is any sort of metal siding, plaster walls with metal lath, foil backed insulation, etc. it's going to be worse.
Every installation is going to be different, so no one can tell you for sure what's going to work and what won't. Only way to know for sure is to try.
But running antennas indoors puts it closer to possible noise sources.
One of the best CA hiway patrol / scanner antennas I ever used was a coax clipped to an aluminum widow frame in a brick office building. My employer tolerated my scanner but drilling a hole might have pushed things to far. Any metal vent or pipe is fair game. Like mmckenna said- only way to know for sure is to try. You might be surprised.
Im very surprised I'm receiving the Pryor site and full scale on the back of set antenna .
I believe that one is a 75 ohm cable. I use this one. It is a 50 ohm through window cable:

Holy Poop! Yeah, 75Ω vs 50Ω in a scanner application isn't going to make a difference. Hell, in most transmit applications, it's not going to make a difference, and certainly not $50 worth.
I've tried my 1/4 wave 18" whip in the window and no signal being received . So back to the back of set and im receiving the Pryor site and 1 bar for the Big Cabin site but not receiving Ottawa county or Anything up in vinita or Miami . But OHP oh ya every where . So for now it'll be the back of set till I get a hole drilled and find a high quality yagi .

the length of the whip on the back of the scanner may have something to do with the reception problem you having.
EX: you only need aprox 6 inches of antenna length for UHF systems, aprox 4 inches for 700/800 systems and aprox 18 inches for 150 mhz systems.
you might be suprised.

Maybe I should just get 1 of those Remtronics rubber duck ?
Me and most of my ham friends route coax to the tower through the soffit vent. You can either cut a hole in that, or loosen one corner to pull the coax through. You will want to then re-attatch the vent snuggly to prevent critters from infesting your attic.

You'll get much better performance out of a dedicated outdoor scanner antenna. It'll make a big improvement and you may find you'll hear things on VHF, UHF and 800 that you never could before. I'd not limit yourself to one band. Install a multiband antenna with good coax and enjoy all your scanner has to offer.
I've already had a discone which was junk . Then thought about a yagi since 800 is all I listen to .
As of now I've got the Pryor site full strength and it's receiving better since i collapsed the back of set antenna down to 6" .
It'll have to do till I figure out a clean install of the equipment .
