After you try that antenna you may want to give a discone antenna a try.
1. A discone is a reasonably wideband antenna which basically means is covers a wide frequency range.
2. The marketing people selling discones advertise that they cover 25 ~ 1300 MHz, and although they do they typically perform poorly at the upper and lower end. Still, that's usually okay for most of us.
3. A discone typically works well enough where most of us listen to transmissions like aircraft, police, fire, rail, business, amateur, military etc.
4. You can find discone antennas from ranging in price from $50 to $700. Are the $700 discone antennas better, possibly but not positively. Is the difference worth $650 more...absolutely not.
I personally have a $50 and $150 discone antenna. I could not tell you which one I was using if you switched them. Usually...hopefully...with more money spent on the antenna, one hopes the antenna is more robust as well to handle snow/ice etc.
Use the most expensive coaxial cable you can afford. Many will recommend LMR-400 and I use it, but I also use RG6 and it works well enough too.
When you mount the antenna, get it above the apex of your roof providing it with a 360 degree field of view, so to speak.
* By the way, you are not the first person to purchase a poor performing antenna. You will not be the last. We live we learn. Have fun!
