The new version antenna optimizes the induction coil upgraded contact shrapnel.added grooves on contact position, so that the contact can be accurately snap on thecoil. The use of manganese steel material increases the strength of the shrapnel,making the contact with the coil more reliable.
The new version coil has marked the number of turns at 20-meter and 40-meterbands, making it easier and faster to set up, even without an antenna analyzer, youcan set up and adjust the antenna easily.

Attention Notes when using the antenna:
1.The assembly sequence of each antenna vibrator is: connecting seat - positive Vcopper piece - two aluminum tubes -inducting coil - pull rod antenna.
2. By using with low transmission power antenna analyzer, in order not affect theadjustment of the standing wave, the feeder line should be all opened, do not circle it.It will have no this kind problem by using higher transmission power antenna analyzer.
3. The side near the pull rod antenna is the first circle. Count from the side with thefixed coil screw. The half circle with the screw is not counted
4. Adjusting the standing wave, Adjusting the SWR, when there is an antennaanalyzer, check the lowest point of the standing wave first. lf the resonant frequencyis over high, it means the antenna is too short, need to pull the rod antenna higher orincrease the induction coil loops. lf the resonant frequency is over low, then to pull therod antenna shorter or reduce the induction coin loops lf there is no antenna analyzer, use the standing wave meter of the radio station, setit in FM, AM or RTTY mode, adjusted the transmit power to about 10 watts, press thetransmit button, adjust the radio frequency knob, and search for the minimum point ofstanding wave on each frequency band, look at the level of resonance frequency, andadjust accordingly.
