Link Speed	Antenna Type		Omni-Directional 7-dBi			Directional 14-dBi
		Cable Length	6m(20 ft) /	22 m (75 ft)		6m (20 ft) /	22m (75 ft)
			15m (50 ft)			15m (50 ft)
	Omni-Directional 7-dBi	6m (20 ft) /	110.2 dB	108.5 dB		110.2 dB	108.5 dB
2 Mbit/s		15m (50 ft)
		22m (75 ft)	108.5 dB	106.8 dB		108.5 dB	106.8 dB
	Directional 14-dBi	6m (20 ft) /	110.2 dB	108.5 dB		117.2 dB	115.5 dB
		15m (50 ft)
		22m (75 ft)	108.5 dB	106.8 dB		115.5 dB	113.8 dB

		22m (75 ft)	111.5 dB	109.8 dB		111.5 dB	109.8 dB
		6m (20 ft) /	113.2 dB	111.5 dB		120.2 dB	118.5 dB
	Directional 14-dBi	15m (50 ft)

The diameter of the 15m (50 ft) and 22m (75 ft) cables is larger than the diameter of the 6m (20 ft) cable. Therefore the cable loss of 50 ft cables is the same as for 20 ft cables, resulting in the same Dynamic Range Budget value.
