About this converter
KVLY runs 629 m in North Dakota, 4 clear of KXTV-KOVR at 625 in California. Hearst at 600 and KCCI at 599 in Alleman follow. WIMZ at 534, Cummins registry at 505, WECT at 497 and WTVY at 488 cluster near 500. Gerbrandy at 375 and collapsed KXJB at 365 close the table. Masts are guyed wire held poles, not freestanding towers. That split matters because tower-height-comparison ranks freestanding only and keeps masts out. KXJB fell in 1968 and is kept only for scale.
How to use it
Pick two masts and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. Try KVLY against Gerbrandy to see the 254 gap. The bars below scale to KVLY so KXJB looks thin next to it. Switch the unit to feet for US figures. Ratios are exact divisions of the mast heights.
Hearst at 600 and KCCI at 599 rank third and fourth above WIMZ at 534, and Gerbrandy at 375 ranks above KXJB at 365 despite draft table quirks. KXJB 365 stood 1966 to 1968 before collapse. Figures follow FCC ASR registry with Dutch specs. Freestanding towers rank on a separate page.
