I'll start by letting everyone know that I'm not an expert. I just recently got into radio frequency scanners, and really love being able to listen in on pilots taking off and landing at the local airports. With the "rubber duck" antenna that came with my scanner I can pick up signals from maybe 3 to 5 miles away, but after switching to the Maldol AL-500H, I can pick up pilot chatter from over 20 miles away while standing in my parking lot surrounded by Apt. buildings and trees. I do live on the second floor... the higher you are with less obstructions, the better signal you'll get. But needless to say I am extremely pleased with this antenna, and the fact that I can sit comfortably in my living room and still pick up traffic from all three airports in my county!

Most HAM operators think of their included rubber antenna as little more than a dummy load. The MH-510 antenna makes a huge difference over the stock unit. This is a well-made product that actually makes a difference on both transmit and receive.
You'll not be disappointed.

To any that are reading this.... the OEM antenna on your radio or scanner is a joke... I would have expected something like this antenna to be included in an expensive scanner...if you are on the fence and think this antenna might not be much better... Don't be fooled. I am not going to tell you it will allow you to pick up transmission from across the state but I can tell you it picks up all the transmission MUCH CLEARER! The range is slightly improved but overall performance is on a completely different level!

This is a nice product. I found it feels a bit long for my Yaesu D8. Works well when outside of cab of vehicle or outside of building, just becuse clearance. My 5 watt radio can now reach a repeater 20 miles away, my factory antenna was not able to touch.

The Rubber duck antenna that came with my Vertex VXA-710 was sufficient enough to lasso the airwaves from the aircraft in the area, but the voices of airbound pilots and those on the control tower / Departure and Arrival / Center frequencies were often scratchy and snowy. Without this antenna you will experience a lot of white noise mixed in with your incoming radio messages. The VXA-710 Radio is showing it's true ability now whenever I attatch this antenna to it. Everything is much clearer and I'm glad I spent the extra money fot this addition to an already great little radio. If you spend several hundred dollars for a transceiver, it's well worth the extra 30-40 dollars to clarify the sound it gives you by buying a high quality antenna. I haven't had my pockets lined by the company who sells this product, I'm a stand alone customer who bought a Vertex VXA-710 that sounded scratchy even at the airport, but was very impressed with the quality of this antenna when used with my radio over the rubber duck antenna that comes in the box.

I bought this antenna for my new scanner to replace the small one that was included. This improved my reception dramatically. I seemed to pick up more signals and the local signals had less static.
One note is that I had to buy a right angle connector to connect to my new scanner (Home Patrol) since the antenna is located on the side of the unit.
I am very pleased with my purchase.

I Bought this antenna for general use. At a local event, I was able to switch to low power to get into the repeater, and get much longer life out of my batteries!
