The 2 meter repeater tower and antennas located next to AD7KV's shop.

2 meter vertical antenna and 440 MHz yagi link antenna.

The 440 MHz yagi antenna. The voter at the Agilent building in Liberty Lake selects the signal from the strongest receiver and sends it to the repeater transmitter via the 440 MHz link.

Since there are no guy wires on the tower, the tower is mounted to the shop wall with a rohn wall bracket for stability.

Ground wires from each leg of the tower go to a seperate 8 foot copper ground rod. Each ground rod is connected together with a buried copper wire, and all the ground rods are connected to the electrical panel ground rod.

Wall pentration for the 2 meter transmitter coax, 440 MHz receive coax, and ground wire. The copper ground wire provides earth ground for the single point ground bus located just inside the shop wall. This wire is connected to an 8 foot copper ground rod.

Tower grounding clamps on each leg of the tower. The ground clamps are made of stainless steel and designed to prevent the copper wire from coming in contact with the galvanized tower. This reduces corrosion between the copper and galvanized tower leg.

The coax shield on each cable is grounded to the base of the tower using a coax cable ground kit.

Lightning suppressors are mounted on a single point copper bus bar located just inside the shop. Grounds for each piece of equipment in the transmitter rack are also connected to this single point ground bus. Earth ground for the bus is provided by one large gauge copper wire that us connected to an 8 foot ground rod outside the building.

The coax from the lighting suppressors go to the transmitter power amplifier and the link receiver. The rack and each piece of equipment in the rack has a seperate ground wire going to the single point ground bus.

Front of the transmitter rack with the exciter on the top, the PA and power supply in the middle, and the transmit filter on the bottom.

440 MHz link receiver and 2 meter transmitter exciter are located inside this case.

Power amplifier and power supply.

2 meter transmitter cavity filter which is used to reduce any harmonics or spurious signals that may be on the transmit signal.

On the top is the back of the case holding the transmitter exciter and 440 MHz link receiver. The yellow cable on the case is the demodulated auto from the link receiver to the exciter. The power amplifier, circulator, and power supply on the bottom.
