17 miCopyable scratchy but readable, at the radio’s bare -116 dBm sensitivity — though the horizon caps it before the power budget does
17 miHorizon geometry stops it here; without this cap the budget alone would reach 39 mi
On a good day, in a good spot, out of a fade, you can be copied out to about 17 mi — the horizon, not the power budget, is what stops it.

🌃 Best evening
11 PM~9.5 mi clean · 5.3 mi solid

Zoomed to 9.30–9.55 mi to show the shape of the day. Clean-audio range changes by 0.1 mi (1.2%) between its best and worst hour.
Normal conditions (0.0/10): the air is behaving normally, and on this link it would not matter much if it were not. Range is capped at 9 mi by clutter and terrain loss, well inside the 17 mi radio horizon — so the weather has nothing to work with. Antenna height and a clearer path will do more here than waiting for a good night.

Radio horizon16.7 mi
Clutter limit9.4 mi
Standard air is −39 N/km (k = 4/3). Below −157 the atmosphere traps signals against the ground. Range is whichever of the two limits above bites first — currently clutter, so weather barely moves it, with antenna heights taken above the measured terrain on this path.

Path-loss models predict a median: half of all spots at that distance are worse. The 90% figure is the one to plan around — nine locations in ten work at it.

Terrain diffraction (P.526)7.2 dB measured
Clutter modelCOST-231 Hata
Every propagation term is computed rather than assumed. At 462 MHz rain and cloud really are four orders of magnitude below the clutter loss — that is the answer, not an omission.

Receiver noise figure8 dB assumed
Slow fading varies between locations, fast fading varies second to second as you move, and body or vehicle coupling is not in any path model because it depends on how the radio is held — all three are real dB and all three are charged here.

Band effectnone
462 MHz sits far above the ionosphere’s critical frequency, so flux and Kp neither open nor close this band — no sporadic-E, no skip. Only the storm-time noise rise is modelled, and only above Kp 5.

ANTENNA GUIDE — WQCP455 · 462.575 MHz · 11.5 mi · geo horizon: 16.7 mi
⚠️ Link is blocked. A higher-gain antenna or taller mounting height may help. Your ERP: 66W.
Element dimensions at 462.575 MHz (GMRS 462–467 band):

1/4-wave Whip (~2.2 dBi)

Length: 6.4". Simplest. Vehicle body or radials needed as ground plane.

1/2-wave Whip (~3.5 dBi)

Length: 12.8". No ground plane needed. Good for handheld upgrade.

5/8-wave (~5.2 dBi) BEST

Length: 16.0". Best gain-per-element. Low angle — ideal for mobile repeater access.

2-el Collinear (~6 dBi)

~30" long. Omnidirectional base antenna. Diamond X50A, Tram 1480, Comet GP-3.

4-el Collinear (~9 dBi) BEST

~5 ft long. +7 dB over rubber duck. Best choice if signal is marginal or blocked.

Yagi Directional (~12 dBi)

Must be aimed at repeater. ~10 dB gain over whip — same as 10× TX power.

🔧 Note: GMRS max power is 50W. LMR-400 coax for runs over 15 ft (~2.2 dB/100 ft at 462 MHz). Every 3 dB of loss halves effective power. Repeater site uses: 2-el collinear / RG-213. Your current ERP: 66W.
