Mr. Vanzwol requested verification of the lattice construction. Mr. Heimdahl explained that the base is somewhat larger than the typical monopole, not supported by guy wires, and requires a 50 foot by 50 foot lease area. Mr. Leiser noted that APT's concern regarding the requirement for approval by a registered licensed engineer concerning radio frequency was understandable, however the physical tower structure should still require approval by a registered licensed engineer. Ms. Page Weed asked if NSP's high voltage line towers could be used. Mr. Heimdahl explained that this again was a function of radio frequency engineering.
Cellular phones use a single band radio wave that runs on one frequency.
There could be interference if the receiving device is placed on power lines. Additionally, existing towers would have to be moved to assure a seamless coverage area. Mr. Welander inquired whether a 165 foot structure would require approval for aircraft. FAA approval and lighting is required only for structures over 200 feet. APT does have an FAA consultant on staff to assure compliance.
