1 HF DTF check does not test antenna. HF DTF check tests the cables from
HF Transceiver to the HF Coupler and the HF connection to the cables via
the Coupler Tray. When HF coupler is de-energized, it connects an internal
50 ohm load to the HF Transceiver RX/TX output. This facilitates testing
from the HF Transceiver without the need to access the Coupler. Test
connection of HF Coupler Tray to HF Antenna to structure using a bonding
meter.
