Our take on the Diamond Antenna D3000N Super Discone Antenna

The Diamond D3000N is a super discone antenna that receives from 25 to 3000 MHz and transmits on 50 to 1200 MHz, with the 6m band tunable for transmit. It is omnidirectional, passive, 50 ohm, and about 67 inches tall at roughly 1 kg, so it can go on a balcony railing where a beam or a tall vertical cannot. Hams use it as one antenna for 2m, 1-1/4m, 70cm, 33cm and 23cm, and as a shop antenna for testing transmitters on a single coax. Its trade-off is nominal 2 dBi gain and modest power handling, so it is a wide-coverage compromise rather than a high-gain band specialist.

Best forApartment and condo dwellers limited to a balcony mountHams who want one antenna across 2m through 23cmTesting several transmitters on a single coaxScanner and wideband receive listening
Pros
  • Very wide coverage: 25 to 3000 MHz receive
  • Transmits on 50 to 1200 MHz, with 6m tunable
  • Omnidirectional, so no rotor or aiming needed
  • Light and compact enough for a balcony railing
  • Top loading coil can be removed to shorten it if low-band receive is not needed
Cons
  • Nominal 2 dBi gain is low next to band-specific verticals
  • Power handling is limited, about 20 W at 50 MHz
  • No coaxial cable included
  • Receive-only above 1200 MHz
  • Height of about 67 inches may still draw attention on a balcony

What reviewers say

Owners treat the D3000N as a versatile wideband antenna that covers many bands from one mount. They praise its broad receive range and balcony-friendly size, and note that it gives up gain and transmit power handling compared with dedicated single-band antennas.

What people mention
  • CoveragePraisedOwners like receiving across a very wide range and transmitting on several ham bands from one antenna.
  • GainCriticisedReviewers say the nominal 2 dBi gain is modest next to dedicated single-band verticals.
  • MountingPraisedIts light weight and size suit balcony railing installs in apartments and condos.
  • Power handlingCriticisedTransmit wattage is limited, especially on 6m, so high-power operation is not its strength.
  • SetupMixedOwners note it needs a separate coax and connector planning since none is included.

From Ham Radio Outlet

  • Ultra-wideband design: 25 to 3000 MHz receive, 50-1200 MHz transmit (6m tunable for transmit)
  • Compact and lightweight design enables installation on a balcony railing at an apartment or condominium
  • Ideal for 2m, 1-1/4m, 70cm, 33cm and 23cm amateur bands
  • Excellent "shop" antenna for testing various transmitters on a single coax
  • Can be made further compact and lightweight by removing the top loading coil if 25-50 MHz reception is not required
  • Nominal gain of 2 dBi

Questions and answers

What frequencies does the D3000N cover?
It receives from 25 to 3000 MHz and transmits from 50 to 1200 MHz. The 6m band is tunable for transmit, and reception above 1200 MHz is receive-only.
Can I use it on an apartment balcony?
Yes. It is about 67 inches tall and roughly 1 kg, and Diamond markets it for balcony railing mounting at apartments and condominiums. Check your building's rules and keep it clear of metal railings where possible.
Does it come with coaxial cable?
No. It uses an N connector and no coax is included, so you supply your own feedline and mount hardware.
How much power can it handle?
Power handling is limited, around 20 W at 50 MHz. Treat it as a low-to-moderate power antenna rather than one for a high-power amplifier.
Can I make it shorter?
Yes. Removing the top loading coil makes it more compact and lighter, but you lose reception in the 25 to 50 MHz range.
Is it good for scanners and wideband listening?
Yes. Its omnidirectional discone design and wide receive range make it a common choice for scanning and monitoring many services on one antenna.
