> Your mileage may vary. When calculating transmitter power for

> attenuation for every flange in the system, regardless of the
> transmission line type. This would give you 6.25 dB loss on
> a 1,000 ft transmission line if you had 20 ft sections of hard-line.
> Andrew's sale "spiel" was that you could save 1/2 your power
> by using one section of Heliax instead of 50 sections of hard
> line.
