Magnum Dynalab SR100 Indoor FM Antenna

What You Need to Know

A Tunable Antenna from the FM Specialists

Magnum Dynalab has spent decades building the world’s most respected FM tuners—so when they design an affordable indoor antenna, it’s not an afterthought. The SR100 “Silver Ribbon” is a folded dipole with a difference: its bright-metal elements telescope up and out from a compact rotating base, letting you tune the antenna itself to each station you receive.

Tuned and Aimed to Defeat Multipath

Indoor FM reception is usually ruined by multipath—signals bouncing off building steel, appliances, and furniture before reaching your tuner. Pull the SR100’s center knob to lengthen the elements and you create a precisely tuned element at the proper impedance for the exact frequency you’re receiving; rotate the base to focus on the main signal instead of its reflections.

Prefer set-and-forget? Shorten the elements and the SR100 behaves as an omnidirectional antenna.

Simple Setup, Surprising Results

The SR100 sits on a shelf or tabletop, connects to virtually any tuner or receiver through its 75-ohm balun and included cable, and needs no installation whatsoever. Reviewers have been floored: Affordable$$Audio found stations once edged with static rendered “quite silent,” and listeners routinely report pulling in stations they couldn’t receive at all. It even doubles as a tunable UHF HDTV antenna.

Frequently Asked Questions

Will it work with my tuner or receiver?
Yes—the included 75-ohm balun and cable connect the SR100 to the antenna input on virtually every FM tuner and receiver made.

How is this better than the wire dipole that came with my receiver?
A wire dipole is fixed in length and taped wherever it landed. The SR100 lets you tune the element length to each station and aim it away from reflections—the two adjustments that actually solve static, hiss, and multipath distortion.

How does it compare to Magnum Dynalab’s ST-2 whip antenna?
The ST-2 is an omnidirectional half-wave whip that mounts outdoors or in a window—the choice for weak-signal fringe areas. The SR100 is the no-installation tabletop solution, ideal in town where multipath, not raw signal strength, is the enemy.
