Diamond Collection D130NJ 25~1300 MHz Super Discone Antenna. Power Rating 144 MHz Up: 200 Watts. 6M: 20 Watts FM, 50 Watts PEP N Connector. Length 5.6'. Gain: 2 (Nominal)

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!

I installed this in my attic using Bolton400 Cable (BT512143) to connect to my Uniden BCD996P2 scanner, mounting it on PBD Adjustable Attic/Outdoor Mounting Pole. I'm pulling in many signals around central Arizona from the Phoenix are to the north and Casa Grande to the south east. Zero issues, assembly took me about 30 minutes and was very simple.

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
