ANTENNA TUNER OPERATION
■ Optional AH-4 automatic antenna tuner operation
The AH-4 matches the IC-7200 to a long wire antenna
more than 7 m/23 ft long (3.5 MHz and above).
• See p. 14 for connection.
• See the AH-4 instruction manual for AH-4 installation and
antenna connection details.
AH-4 setting example:
For mobile operation
For outdoor operation
Long wire
Optional AH-2b
antenna element
R DANGER!: HIGH VOLTAGE!
NEVER touch the antenna element while tuning or
transmitting.
NEVER operate the AH-4 without an antenna wire.
The tuner and transceiver will be damaged.
NEVER operate the AH-4 when it is ungrounded.
Transmitting before tuning may damage the trans-
ceiver. Note that the AH-4 cannot tune when using a
1
⁄2λ long wire or on a multiple of that frequency.
D AH-4 operation
Tuning is required for each frequency. Be sure to
re-tune the antenna before transmitting when you
change the frequency—even slightly.
q Set the desired frequency in an HF band.
• The AH-4 will not operate on frequencies outside of
ham bands.
w Push and hold
TUNER
for 1 sec.
• “ ” indicator blinks while tuning.
e “ ” indicator is still ON after the tuning is
completed.
• When the connected wire cannot be tuned, “ ”
indicator goes out, and the AH-4 is bypassed and the
antenna wire is connected to the antenna connector
on the transceiver directly.
r To bypass the AH-4 manually, push
TUNER
.
• “ ” indicator goes out.
Appears when the antenna tuner ON.
Blinks while tuning.
CONVENIENT
• PTT tune function (p. 76)
The AH-4 is always tuned when [PTT] is pushed
after the frequency is changed (more than 1%). This
function removes the “push and hold
TUNER
” op-
eration and activates first transmission on the new
frequency.
This function is turned ON in the set mode.

- As different exposure limits have been recommended for different frequencies a relative table shows a guideline for installation considerations 100
- Below 30 mhz the recommended limits are specified in terms of v m or a m fields as they are likely to fall within the near field region similarly the antennas may be physically short in terms of electrical length and that the installation will require some antenna matching device which can create local high intensity magnetic fields analysis of such mf installations is best considered in association with published guid ance notes such as the fcc oet bulletin 65 edition 97 01 and its annexes relative to amateur transmitter installations the ec recommended limits are almost identical to the fcc specified uncontrolled limits and tables exist that show pre calculated safe distances for different antenna types for different frequency bands further information can be found at http www arrl org 100
- For amateur base station installations it is recom mended that the forward clearance in front of the an tenna array is calculated relative to the eirp effec tive isotropic radiated power the clearance height below the antenna array can be determined in most cases from the rf power at the antenna input termi nals 100
- For the bands 10 mhz and higher the following power density limits have been recommended 10 50 mhz 2 w sq m 100
- Forward clearance by eirp output 100 watts 2 m 1000 watts 6 m 10 000 watts 20 m 100 000 watts 65 m 100
- In all cases any possible risk depends on the trans mitter being activated for long periods actual recom mendation limits are specified as an average during 6 minutes normally the transmitter is not active for long periods of time some radio licenses will require that a timer circuit automatically cuts off the transmitter after 1 2 minutes etc 100
- Installation notes 100
- List of country codes iso 3166 1 100
- Similarly some modes of transmission ssb cw am etc have a lower average output power and the as sessed risk is even lower 100
- The figures assume the worst case emission of a constant carrier 100
- This warning symbol indicates that this equipment operates in non harmonised frequency bands and or may be subject to licensing conditions in the country of use be sure to check that you have the correct version of this radio or the correct pro gramming of this radio to comply with na tional licensing requirement 100
- Typical amateur radio installation exposure distance assumes that the predominant ra diation pattern is forward and that radiation vertically downwards is at unity gain sidelobe suppression is equal to main lobe gain this is true of almost every gain antenna today exposed persons are assumed to be beneath the antenna array and have a typical height of 1 m 100
- Versions of the ic 7200 which display the ce symbol on the serial number seal comply with the essential requirements of the european radio and telecommunica tion terminal directive 1999 5 ec 100
