Description

This modification responds to varies questions. QUESTION 1) What is the size/type or model of the antenna? ANSWER: The antenna load is equivalent to a 4-foot Tecom dish. QUESTION 2) Is there a low temperature requirement? ANSWER: Low temperature is not usually our first concern, but 0 degrees F will do. QUESTION 3) Will there be any accommodations for RF channels through the system either waveguide or Coax and at what power, frequency and losses? ANSWER: The government is responsible for mounting the antenna and will provide the coaxial RF cables to and from the dual channel rotary joint with SMA connections. The dual channel rotary joint is to be integrated into the pedestal system. The frequency range from DC to 18 GHz. The Kevlin rotary joint that was suggested or equivalent has the RF characteristics we are looking for. QUESTION 4) Are the users 18 slip ring circuits all low voltage DC (with 6 at 3 amps) or is higher voltage/power required? ANSWER: Fourteen (14) slip rings are low voltage and current. Four (4) slip rings need to handle 60-cycle power and a minimum of 7 amps. QUESTION 5) What is the distance between the controller and pedestal? ANSWER: The distance between the controller and the pedestal is forty (40) feet. QUESTION 6) Are cables to be supplied? ANSWER: The control and interface cables must be supplied with the antenna pedestal. The government will provide the RF cables. QUESTION 7) With regards to the controller, which operating modes are desired? ANSWER: We did not specify software modes, purposely. We did specify how often the pedestal would be updated. At a minimum, the pedestal/controller will be given a new position to go to every 100 milliseconds. Consequently, there has to be some reasonable way to interface to the controller and we have specified those requirements in form and speed. The solicitation closing date remains 7 December 2000.
