Lower noise maybe? Thank you for any advice
Low band can be difficult to receive. Antenna can make a big difference.
Start out using it as is. If you need to improve reception you can cut off a little at a time.
Back in the days when I was listening to 33 / 39 Mhz. I would cut down CB antennas which worked very well.
