11) An HF wire antenna will have Report

weak link and tensioning unit at the rear tethering point

A weak link and tensioning unit at the feed through antenna stand off mast end

A weak link at the feed through antenna stand off mast end and a tensioning unit at the rear tethering point

12) If an HF controller has a function switch position marked �AME� then this would be selected to receive Report

an amplitude modulated wave with carrier and two sidebands only

SSB with full carrier only

an amplitude modulated wave with carrier and two sidebands or SSB with full carrier

13) When selecting a new HF Comm frequency Report

so as not to create safety hazard, the ATU will only tune when HF mic is selected, the PTT switch is pressed and the operator speaks into the mic

a tuning sequence starts which involves generation of transmitter power so safety precautions must be observed

The ATU is tuned but no RF is fed to the antenna until the PTT switch is pressed

14) H.F. radio antennae couplers are used to Report

switch the antenna signals between receive and transmit

"tune" the electrical length of the antenna to the frequency being used

connect two sections of antenna cable when they pass through an aircraft bulkhead

15) Anyone operating HF equipment on the ground should Report

have an observer in the cockpit

ensure nobody is working near the HF antenna

not operate VHF at the same time
