ATU-130 is a 150w automatic antenna tuner. Improved on the basis of ATU-100 hardware, it is an universal type.<br>Adopt PIC18F2520, MCU<br>Using 4pcs T94 magnetic ring inductors, the coil above 1mm, the withstand power is greater, and the heat is much smaller than <br>Use HF32, 10A, HF33, 5A relays (similar to that for icom at130)<br>Adopt 6KV high-voltage capacitor with low loss. Miniature shortwave automatic antenna tuner<br><br>Parameters:<br>Coverage frequency: 3.5-54MHz<br>Tuning impedance range: 5ohm-1.2Kohm<br>Tuning power: 5-15W<br>Transmit power: SSB 160w max<br>Maximum measurable power: 180w<br>When the initial standing wave deviation is , it is recommended to use the SSB not more than 150w for a long time. (FT8, AM, FM, CW is not more than 100W. When the deviation of the standing wave before adjustment is , reduce the power as appropriate)<br>Size: 38 x 88 x 155mm/1.5 x 3.5 x 6.1inch (without the size of protrusions)<br>Power supply: 11-14VDC power supply<br>Instructions:<br>Connect the power cord to 11-14vDC power supply. Connect a shortwave radio to the IN RF line of the automatic tuner. The antenna is connected to the ANT of the antenna tuner (M seat or quick socket). With Am, fm, cw 6-15w well tuned (within swr1.5), you can use high power.<br>If the standing wave is too and the tuning is not successful, high-power transmission cannot be used, because it may damage the antenna tuner or shortwave radio. Please remove the fault and then transmit with high power.<br>Good grounding is good for standing wave tuning. If it is unconditionally grounded, connect the grounding end of the tuner to the grounding of shortwave radios.<br>Colour:black+blue<br>Material:Metal<br><br>Package Contents:<br>1 x Antenna Tuner<br>1 set x accessories (random colors, don't accept the specified color)<br><br>Only the above package content, other products are not included.<br>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
