As a rule of thumb, the spacing of pipe supports for steel pipes in liquid service, expressed in feet, may be taken as the nominal pipe size, expressed in inches, plus ten. For example, the spacing of pipe supports on a 6 line will be approximately 6 + 10 = 16 feet. This spacing changes at high temperatures and for materials other than steel. For example, for copper tubing, support spacing varies from 8-ft for 1 tubing to 12-ft for 4.
line of sight, that is, the receiving antennas should be directly visible from the transmitting position. Antenna Spacing Antennas should be separated from each other by a minimum of one quarter wavelength â about 16 inches (40 cm) for VHF units and about 4 inches (10 cm) for UHF units. This helps ensure adequate diversity performance. Diversity reception can be improved by separating the antennas further, but beyond one full wavelength the advantage becomes negligible.
