Condition:New
Type:Logic ICs
Model Number:M-130A
? ? ? ?The M-130A antenna has been upgraded 5 times on the basis of the M-120A, and it is also the most thorough one. It has a new commercial design, a new antenna structure, and the quality of the parts is perfect. No DIY traces can be found. The internal structure, parts The quality has surpassed a big brand, and the price is only 1/3 of theirs.
? ? ? ?On the basis of the original M-120A, 3.5Mhz and 5Mhz frequency bands are added, 3.5--54Mhz are continuously adjustable, and the antennas are all retracted to the 144/433mhz frequency band.
? ? ? ?The diameter of the coil is thickened to 32mm, and the contact method is also more reasonable and firm (the contact sheet is punched by beryllium copper, and the process is very complicated). The Q value of the newly designed coil is much higher than that of the 120A antenna, and the DC resistance of the M-130A antenna coil is Less than 1 ohm (Yaisu ATAS-120A is 6 ohms), the smaller the antenna coil resistance, the smaller the loss, and the stronger the radiated signal.
? ? ? All antenna parts are produced by open mold or CNC machining center, the consistency is very high, and the error of each part is about 0.05mm.
? ? ? ?The antenna vibrator can replace the rod antenna of the M10 interface, which improves the efficiency of 3.5/7mhz and makes it more playable.
Specifications:

? ? ? ? 3.5Mhz - 450Mhz car shortwave antenna, auto tuning. Fully compatible with YAESU Yaesu FT-857D, FT-450D, FT-897D, FT-991, FT-891. Only use one feeder to connect to the radio, no need to connect the power supply and data cable separately, set it in the menu of the radio, press the TUNE button on the panel, automatically control the rise and fall of the antenna, and automatically stop when the best standing wave ratio is reached.
It does not matter if it is not the above model radio: there is an AX-17 shortwave antenna automatic controller to achieve automatic control.

The ground net is very important. It can be connected to the car shell screws with copper braided tapes. The shorter the length, the better.
Tuned antenna on 144Mhz/433Mhz Fully retractable, boxed.
For FT-857D, please do the following:
1. First long press the FUNC key to menu No. 1, and change it to ON (open the extended menu);
2. Go to menu No. 85, use the big knob to select ATAS (ALL);
3. Long press the FUNC key to save the settings.
4. Short press the FUNC key to adjust K , the display shows TUNE , DOWN , UP .
5. Press and hold the A key, hear a BI sound, and the display shows INIT, indicating that it is initializing (it will be completed automatically).
6. After waiting for the initialization (up to 60 seconds), the antenna will automatically find the resonance point.
7. Adjust to the frequency you want, and long press the A key to make new adjustments.
-------------------------------------------------- ---------------
8. Manual adjustment: adjust to FM mode, press the hand microphone PTT transmit power, and then press the B or C key (corresponding to DOWN / UP), the antenna will move up and down.
The manual mode is only used to fine-tune the position of the antenna to obtain a lower SWR, and it is not recommended to move the antenna up and down for a long distance.
