Our take on the Scanner Antenna/Discone Antenna/GMRS Antenna with 10meter Cable PL-259 SMA, 25~1300 MHz Support CB, HF, AIR, UHF, VHF, FM, AM, FRS, GMRS, 1090MHz

The Signalplus Discone is a wideband vertical antenna that covers roughly 25 to 1300 MHz, so one mast-mounted unit can serve scanners, CB, ham HF/VHF/UHF, airband, FRS/GMRS and 1090 MHz ADS-B reception. It is rated at 200 W with 50 ohm impedance and SWR under 1.5:1, and it ships with a 10 m coax run terminated PL-259 male to PL-259 female, plus mounting hardware. The discone design trades gain (3.5 dBi claimed) for bandwidth, so a dedicated single-band antenna will usually outperform it on one band while this covers many. Owners describe it as well built from stainless steel and aluminum and performing as advertised; at about 1.7 m tall and 1.35 kg it needs a sturdy mast and decent height for best range.

Pros
  • One antenna covers 25–1300 MHz
  • Handles up to 200 W
  • SWR under 1.5:1 across the design band
  • Stainless steel and aluminum construction
  • Includes 10 m coax and mounting hardware
Cons
  • 3.5 dBi gain is modest next to band-specific antennas
  • Large 1.7 m footprint needs a solid mast
  • 10 m cable may be short for some roof runs
  • PL-259 to PL-259 cable needs an adapter for SMA radios

Questions and answers

What radios and bands does it work with?
It is a receive-and-transmit discone covering about 25–1300 MHz, so it suits scanners, CB, HF/VHF/UHF ham, airband, FRS/GMRS and 1090 MHz ADS-B. It is vertically polarized and rated to 200 W.
What connectors does it use?
The antenna has a UHF female (SO-239) socket, and the included 10 m cable is PL-259 male to PL-259 female. Radios with an SMA jack need a PL-259 to SMA adapter.
How high should I mount it?
Higher is better for range; a rooftop or mast mount clear of obstructions works best. The 1.7 m, 1.35 kg antenna needs a sturdy mast and the supplied hardware.
Is it good for transmitting or mainly scanning?
It handles up to 200 W and SWR under 1.5:1, so light transmitting on CB, FRS/GMRS and ham bands is fine. Its 3.5 dBi gain means a band-specific antenna will beat it on a single band.
What is in the box?
The discone antenna, mounting hardware and a 10 m PL-259 coax cable. Check that the cable length reaches from your mast to the radio.
