Responses to your inquiry are below:

Please provide the following information in reference to requested channels 3 and 4:

1. Television channel number(s).

Channels 3 and 4 (actual transmitting frequency would be at bottom of channel edge)

2. Antenna location site elevation above mean sea level in meters.

1150m ASL

3. Overall tower height above ground level/above average terrain in meters.

2 meters above ground level maximum

4. Height of radiation center above ground level in meters.

2 meters above ground level maximum per license grant

5. Maximum effective radiated power in kilowatts (Peak):

.5 kW ERP per license grant

6. Transmitter output power in kilowatts.

1 kW max

7. Verify that the antenna is nondirectional (if directional, please report the directional
antenna's relative field value at every 10 degrees from 0 through 350 degrees).

Antenna is nondirectional (wideband biconical)

8. If the emissions are digital, then report the out-of-band emission mask (simple or stringent).

Emissions are analog

9. If the emissions are analog, then report the frequency offset (zero, plus, minus or none).

Emissions are an unmodulated carrier (N0N) or 80% 1 kHz AM modulation (2K00A3E - 2 kHz
max bandwidth) at a transmit frequency 2 KHz above the bottom channel edge to minimize any
interference. This should result in interference levels significantly lower than even an offset cochannel
station
