DULUX TUNNER KIT.
By Mark L. Meyer
>
Here is a 10-15 watt antenna tuner kit
This antenna tunner covers from 3.5-30mhz and with a little more inductance and capacitance would cover 160 meters....
This tunner also will work for those that want a tuner for SWL or for those that are into QRP and need a 10-15 watt ant tuner.
This is your basic T-Type antenna tuner and also you could add a small 4:1 balun and make it even better
PARTS LIST BELOW
- 2 SMALL 240 PF Poly caps.
See photo on how to connect the sections of the poly caps in Parallel to get 240pf..also..make sure ..make sure you use the 3 lugs on poly cap where it says R.O.C. X N....Just look at photo with meter and you be ok..better yet..right click the photo and save to your pc for a reference.Also just remember to hook a piece of hook up wire from one outside lug on cap to the other out side lug on cap..then you will have only 1 connection to either left or right on out side of cap and one connection to center lug on cap.
of course you have to solder the wires to the cap.
Please note that the little lugs on poly caps do not take a lot of bending back and forth..or they break..just something more to remember.
Just take your time..refer to fig 1 on instruction page and you will be ok.
One more thing..when you are using to tuner to adj a ant to your little transmitter..start out with the smallest out put you can and work your way up to your total output...all ant's do not tune up the same.So what you have to be aware of when using small caps like these is not to blow the plates and if you take your time and use tunner correct the little caps will take 10-15 watts if you have a decent swr.
- 1 PIECE 1 POLE-12 POSITION ROTARY 1/4" Shaft Switch with all mounting hard ware
