Wideband listening &mdash; antenna choice depends on your target frequency

<ul style="margin: 6px 0 0 14px; padding: 0;">
<li><strong style="color: var(--text-primary);">Best range:</strong> 800 MHz&ndash;1.2 GHz (tuned near 1 GHz)</li>
<li><strong style="color: var(--text-primary);">Usable for:</strong> Airband, trunked radio, cell bands</li>
<li><strong style="color: var(--text-primary);">Poor below:</strong> ~400 MHz (too short for VHF/lower UHF)</li>
</ul>

<strong style="color: #00ff88; font-size: 12px;">Discone (Best All-rounder &mdash; ~$30-50)</strong>
<ul style="margin: 6px 0 0 14px; padding: 0;">
<li><strong style="color: var(--text-primary);">Coverage:</strong> ~25 MHz to 1.3 GHz continuous</li>
<li><strong style="color: var(--text-primary);">Gain:</strong> ~2 dBi (modest but consistent across bands)</li>
<li><strong style="color: var(--text-primary);">Polarization:</strong> Vertical omnidirectional</li>
<li><strong style="color: var(--text-primary);">Placement:</strong> Outdoors, as high as possible</li>
</ul>

Ideal for scanning &mdash; covers VHF, UHF, airband, marine, public safety, and more in one antenna.

<ul style="margin: 6px 0 0 14px; padding: 0;">
<li><strong style="color: var(--text-primary);">Formula:</strong> Element length (cm) = 7500 / frequency (MHz)</li>
<li><strong style="color: var(--text-primary);">Example:</strong> 155 MHz police &rarr; 48.4 cm per element dipole</li>
<li><strong style="color: var(--text-primary);">Example:</strong> 460 MHz UHF &rarr; 16.3 cm per element dipole</li>
<li><strong style="color: var(--text-primary);">Higher gain:</strong> ~3&ndash;5 dBi better than discone on target freq</li>
