After saw Mr Richard I traveled every electronics shop at Butterworth, I just got small ferrite ring and after a few shop lastly I find big feerite ring that suitable for my new project. I'm very happy and bought everythings that needed. The day after tomorrow I started my projects and after some trials I got good result like Mr Richard got. This antenna does not require a tuner and which is acapble of porviding reasonable performance on all bands from 7MHz to 28MHz but reduce performance from 3.5MHz to 51MHz). For more informations you can visits website Martin - G8JNJ. You can try it.
You have to make 5.1 RF Transformer
Ferrite rings and copper tubes
Put the copper tube inside the ferrite ring to make 5.1 RF Transformer
Two tubes of cooper inside the ferrite ring and make 5.1 RF Transformer
Put the transformer inside PVC pipe
This is 5.1 RF transformer
Build 1.1 balun for this antenna.
You can use five of the same ferrite rings glued together with five turns of coax through the ferrite.
Put it inside the PVC pipe and finish for 1.1 balun
The antenna from the fishing pole(telescopic). You need :
1. 8metres fishing pole(rod)
2. 22 feets 8 inches long stainless steel wire(5mm diameter) or copper wire or any wire you have.
Clip the 5.1 RF Transformer to the fishing rod
Put the stainless steel or any wire inside the fishing rod straigh from bottom to top or you can tie wrapped it outside by masking tape every 2 or 3 feet to prevent from moving. Clip the fishing rod to the aluminium pipe or any pipe. Don't forget to joint the cable from 5.1 RF Transformer to 1.1 balun and direct to you radio. After that connected outer coax braid to earth on 'radio' side of balun. Now you can try to transmit you new antenna. My antenna was high up just 20 feet but can copy many stations from Europe, Middle East, Japan, China and others through 20metres (14MHz). For me it's perform good for 20metre and 40metre. For 10metre, Delta Loop antenna perform better. You can make it as permanent antenna at your base or as a portable by using the telescopic fishing rod(can make it short) OK. that all for Vertical antenna, you can try it yourself.
