Multi Band mini-buddipole HF Shortwave GP Outdoor Portable Antenna QRP For Ham Radio JPC-7

The JPC-7 is a mini portable antenna specially designed for field communication. The installation is simple and quick and one person can be set up the antenna in minutes.

This new vertsion has a new optimized inducion coil which has a shrapnel pin added. This has Increased the strength of the shrapne and made to contact better with the coil and is therefore more reliable.

The new version of the coil has the band band marked on the coil.

Even without a Antenna analizerr, the antenna can be easily erected and adjusted.

When using the 20m band only needs to move the slider contact to the gold mark position and then shorten the unilateral pull rod antenna about 10cm

Finally, fine-tune the lever antenna according to the frequency of your use. The 40 meter band moves the slider contact to the silver Mark position.

The pull rod antenna can be used directly after being pulled out.

Mini-Buddipole Antenna is a mini version of small portable antenna specially designed for field mobile communication.

It is completely made according to the original standard.

The antenna can be used on the following bands 2,6,10,12,15,17,20,30,40M.

The dipole legs can be contracted to a length of 34.5CM

The two The telescopic antenna parts can be expanded to a lenth of 6.6M,

The size of the bag is:37cm x 23cm  and Weight 1.8kg,

Easy to carry and set up all you need is just a support rod and tripot and suport lines and coaxle feed line.

An additional ground plane net can aslo be used but is not supplied.

Antenna :

1. The assembly sequence of the antenna: connection base-two aluminum tubes-induction coil-pull rod antenna

2. When U are using low power QRP you should not coil your feedline to the radio otr ATU as this will afect your SWR. If you are using it for high power the coaxle cable coiling will not matter.

3. On the coile the first side near the rod antenna is the first circle, counting from this end of the coil. Do not count the half circle with the screw.

4. When adjusting standing wave, find the lowest point of standing wave when there is a swr meter, and see if the resonance frequency is high or low. If the resonance frequency is high, it means that the antenna is to short. Increase the number of coils of the induction coil. If it is low, shorten the rod antenna or reduce the number of coils of the induction coil.       

If there is no swr meter, use the standing wave table that comes with the radio, set it to FM, AM or RTTY mode, reduce the transmit power to about 10 watts, press the transmit button, adjust the radio frequency knob, and look for each frequency band. The minimum point of the standing wave, look at the level of the resonance frequency, and then use the appeal method to adjust

Reference data:

40-meter band: 7.050-Starting from the side of the aluminum tube are the 5th circle and the 4th circle (positions marked with silver).

20-meter band: 14.270- The 7th and 9th circles (golden marked position) are counted from the side of the rod antenna. After pulling out the 10 sections of the rod antenna, shorten the rod on one side by about 10cm. Standing wave 1.0-1.2 It is to shorten the rod antenna on one side, and the other side does not need to be adjusted.

15-meter band: 21 Mhz are two turns on each side of the rod antenna, and the rod is all pulled out

10-meter wave band: Pull out all ten sections of the whip antenna, and then retract one of the whip antennas to about 7cm, 29.600 standing wave 1.2

Note: Half circle with a screw is not counted
