Indoor is tough, since you dont say what bands you are trying to pick up. If you have a indoor tv antenna with a 75 ohm coax you could get an adapter for your scanner and try that. If you are trying to get a specific band, you should be able to find a 1/4 wave or 5/8 wave whip for your scanner which will work better than the helical duck that comes with them.
For best results tho, you really need to get one outside.
Where do you plan on putting the antenna? Indoor could mean many things. I have an antenna in the attic, so that would be an indoor antenna. What frequencies are you trying to receive? That will also affect your options.
What scanner? What antenna are you using? Monitoring Delaware county? Could they have narrow banded their conventional analog frequencies? Listening to Powell on the 800MHz repeater? All questions that can make the right antenna choice. HTH, Larry
The scanner being used doesn't matter that much. What's important as far as antenna is concerned:
- What bands are you listening to
- Are all the signals directional from you, or do you need omni-directional
- How much space do you have for this indoor antenna
I am using it during college in Athens Ohio. I need to listen to a couple Ohio marcs frequencies, along with several in the 150 FM band, such as local police, which are the ones I am trying to improve reception of. I am using a pro-106 scanner. I will be putting the antenna inside my studio apartment.

First suggestion given in this thread was prob a good one: Use a TV antenna. Solid Signal sells a flat antenna you can put right against a window. $20. Put it in a window on an upper floor that is in the direction of your nearest MARCS site. Use a female F to SMA adapter or whichever matches your scanner. Run the coax to your scanner. Simple, inexpensive, and potentially very effective.
