D130NJ Diamond Antenna Super Discone Antenna – Wideband High-Performance Scanner and Radio Signal Reception for Amateur, CB, and Mobile Communication

This antenna is a solid performer for both scanning enthusasts and amateur radio operators. I have had this antenna installed since mid-summer 2025 on a three-story building's roof and am able to hit repeaters 70 miles away. Obviously, your performance will depend on operating conditions. If the technical charactaristics of this antenna match your needs I highly recommend it. Assembly was straighforward and can be accomplished by one person in about 45 minutes.

The Diamond D130NJ performs exactly as expected. It is well-constructed, sturdy, and delivers consistently stable SWR across its entire frequency range. The build quality is excellent, making it a reliable choice for those who need a dependable wideband antenna. Highly recommended!

Good reception. More bandwidth and better reception than my old spider antenna.

I bought the N connector version..as most of my uhf ham gear is N. Time consuming assembly.. Wear safety glasses.. Lots of little parts.. I was stunned buy the performance..wow.. Works well..I used it on 10m for a distant contact..lol...it is 6m 50mhz to 1.2 ghz range.. I highly recommend

For the money I’m very pleased with this antenna. At times I can receive signal from over 60 miles away on my SDS200 scanner. If you want an antenna that works and won’t break the bank I would recommend this one.

For many years this company has been making antennas for us radio nuts and they have always held up and performed well for me and a lot of my friends.

Looks like someone raided the package before it was shipped. At least six parts missing. Didn't even bother to try and assemble. On the plus side, the parts that were there looked well made. Probably could have been a good antenna.

Dedicated to my Uniden SDS200 Scanner, simply one of the best wideband coverage discone antennas made.
