The VOR/LOC antenna is a combined VHF Omnidirectional Range and localiser antenna.
We need to work on the top of the tail so we get some safety harnesses and a telescopic personell carrier.
My colleague Dennis picks up the new VOR/LOC antenna out of the box.
The forward section of the VOR/LOC antenna first needs to come off to get good access to the coax connectors.
The front panel removed from the VOR/LOC antenna, we can disconnect the coax connectors.
Dennis unscrews the screws that hold the anntenna in place.
And the antenna comes off.
The top of the tail with the antenna removed.
We move away from the tail to go down to the ground to prepare the new VOR/LOC antenna.
We need to transfer a static wick from the old antenna to the new one.
On both sides of the old VOR/LOC antenna, the bonding plate was bent causing a improper bonding on the structure.
We fit the new antenna paying close attention to the grounding plate.
We tighten the antenna again.
Connect the coax connectors and close up the front panel of the antenna.
After replacing the antenna we need to do the VOR/ILS/MB system test so we get the T-30C testset.
To see what's included into this test go to the VOR/ILS/MB testset page in the avionics tools section.
