Our take on the Pulse Larsen 400-512 MHz Tunable Antenna BNC 6 SPWH15FT

The Pulse Larsen SPWH15FT is a tunable VHF whip antenna covering 400–512 MHz with a BNC connector and a 15-foot cable. It is a panel-mount design aimed at radios in the UHF business band, public safety and amateur use. Unlike fixed-length whips, it tunes across the band so you can trim it for the frequency you actually use. It is a utilitarian part, not a consumer gadget: buy it for fit and frequency coverage, not styling.

Pros
  • Tunable across 400–512 MHz, so it can be trimmed to your frequency
  • BNC connector mates with common handhelds and mobile radios
  • 15-foot cable lets you place the antenna away from the radio
  • Straight whip with panel mount for fixed installations
  • Compact 152 mm length keeps a low profile
Cons
  • Tuning requires trimming, which is permanent
  • BNC is less secure than threaded connectors in high-vibration use
  • Narrow band coverage means it is not a general-purpose scanner antenna
  • Panel mount needs a drilled hole or bracket

Questions and answers

What frequency range does it cover?
It tunes across 400 to 512 MHz, the UHF business and public safety band. Trim it for the frequency you transmit on.
What radio connector does it use?
It terminates in a BNC connector, common on handhelds and many mobile radios. Check your radio's antenna port before buying.
How long is the cable?
The included cable is 15 feet, which lets you mount the antenna away from the radio.
Do I need to tune it?
Yes. It is a tunable whip, so you cut it to length for your operating frequency. Measure and check SWR before final trimming.
Can I use it as a scanner antenna?
It will receive across its range, but it is built for transmit on a specific frequency. A dedicated wideband scanner antenna covers more.
What mounting does it need?
It is a panel-mount design, so plan on a drilled hole or bracket. The 152 mm whip is short enough for tight spaces.
