Non-Scientific Aerial Testing: A Quick Look at Reception Performance

Recently, I carried out a little backyard experiment to test how different types of antennas perform when receiving various radio frequencies. It wasn't a lab-controlled environment, nor was it strictly scientific—but it was practical, fun, and surprisingly informative.

The Setup

Location: Home, radio desk.

Tested Equipment:

  • UBC-73XLT (Standard Antenna): A general-purpose handheld scanner

  • TV Rabbit Ears: The classic indoor adjustable antenna—nothing fancy. Added a BNC connector.

  • VHF Marine Antenna: Typically used on boats; designed for marine VHF but tested here for broader reception. Roof-mounted at ~3 meters off the ground



Each antenna was tested for signal reception quality across various frequencies from the Tasmanian Government Radio Network (TASGRN), TasRail, and some data services. Ratings were on a basic 0–5 scale, representing relative signal strength and clarity:    

  • 0: No signal

  • 5: Excellent reception

Takeaways

This test reinforced a common truth in radio: antenna choice matters more than your receiver. Even a high-quality scanner can be let down by a poor antenna. If you're relying on a stock antenna for critical reception—especially in rural or fringe areas—you’re likely missing out on a lot.

The VHF Marine antenna proved to be the best all-rounder in this setup. Mounted just 3 meters above ground, it provided clear and strong reception across the board. If you're into scanning and have the space to mount something outdoors, it’s worth considering a purpose-built antenna—even one designed for marine use.


Final Thoughts

While this wasn't a lab test, and environmental variables weren’t controlled, the results are still quite telling. If you're using a handheld or base scanner and wondering why your reception is lacking, start by looking up—your antenna might be the real bottleneck.
