If you could reply and advise of what frequencies or bands you monitor, it will help others on providing advice, good or bad
Off we go with general antenna info: ( While these types are typically used outdoors, you could try indoors as well )
1. An omni directional antenna specific to the band you want to RX usually provide gain, thus improving your chances of RX.
2. A Yagi antenna is directional and typically tuned for a particular band and also offers gain.
3. A discone antenna covers more bandwidth, but is unity gain (Typically much less gain than #1 or #2 above) Still, if you can hear the signals when you go outside with the 1040 and it's stock antenna, the discone may work fine for you.
For those who for whatever reason can't set up an outdoor antenna, this setup works quite a bit better than a ducky/whip. Antenna: https://www.amazon.com/gp/product/B00QVPGKHU/ Stand: https://www.amazon.com/gp/product/B000E0PPG0/ The stand tubing is the exact right size to fit the antenna...
