Antenna Considerations; Fts-17A Tone Squelch Unit Installation - Yaesu FT-411 MKII Operating Manual

Accessories & Options
While the supplied YHA-16 rubber flex antenna is convenient for short-range operation,
the standard BNC connector allows use of a higher gain antenna for extended range base or
mobile operation. However, any antenna used with the FT-411
ance close to 50-ohms on the 2m band. Also, if the antenna is connected with a feedline,
use only good quality 50-ohm coaxial cable. To obtain a proper fit with some BNC plugs,
you may need to remove the rubber gasket around the antenna jack on the transceiver.
FTS-17A T
The FTS-17A is a subaudible CTCSS (Continuous Tone-Controlled Squelch System) which
offers programmable selection of 38 tones for transmission and filter/detectors for recep-
tion. Transmit-only (encode) and transmit/receive (encode/decode) modes are selectable
from keys on the transceiver.
Make sure the transceiver is off. Remove the hard or soft case, if used, and remove the
battery pack.
