No engineering drawings available.

4. Do you have a particular model number for the 28 foot tall antenna?

No.

5. What antennas are currently on tower?

4 bay VHF antenna, 1 UHF Omni, 3 mobile mount dual band antenna.

6. What are the heights of each antenna including the new one?

New VHF antenna is 43 feet, UHF is at 42 feet approximately, all others antenna shall be removed once the new one is in place.

7. How many frequencies need to be combined?

6 sets.

8. What are the frequencies that need to be combined?

Information will be provided to the selected contractor but the frequencies shall operate in the range of 136‐174 MHZ on the military band side.

9. What type of “System” is being requested? Is it a Conventional Repeater system, or Trunking Repeater system?

P25 Conventional Repeater.

a. If Conventional, what is the quantity of repeaters required?

Shall be a system composed of 6 repeaters.

1. What are the number of sites?

1 Site located in Camp Santiago Joint Training Center, Salinas, Puerto Rico

2. How many repeaters per site?

3. What is the VHF frequency pairs (TX & RX) to be used?

Information will be provided to the selected contractor but the frequencies shall operate in the range of 136‐174 MHZ on the military band side.

b. If Trunking, is it Phase I or Phase 2?

No Trunking required.

10. Codan SR‐39‐1 is not a repeater, but a Rack used for the Codan Repeaters.

a. Do you have Codan Repeaters now?

Yes we do.

b. If so, how many?

Total of 8 repeaters.

c. If so, do you need additional repeaters to work with the Codan repeater (see #1.)

11. What are the measurements dimensions of the existing tower (needed for extension)?

ROHN 25 of 45 feet high.
