![]() "Andy" wrote in message ... Hi Dave I am new to all this. I have heard that the tuner might have problems tunning on all bands if I don't use a 4:1 balun. Are you saying that I don't need a balun just a choke? What sort of choke would you reccomend buying for the job? Thanks Andy Andy - I went through this with the group a few weeks ago. I wound up winding 9 turns of rg8x coax around a 2-1/2" form giving a coil with a 2-5/8" diameter (at the centerline of the coax). I ended up with an inductance of 4.798 uH. If you made the coil bigger it might be better - some on this group expressed worries that such a tight coil would have problems with the center conductor migrating to the inside of the coil...... I simply used a form that I had. After winding the coil, I glued it together with superglue, dusted with baking soda (to set the glue instantly)...... BTW my antenna is a 153'2" dipole, wrapped around a brick building - the antenna tunes 1.8-30 mhz with a Z11 tuner just fine. The antenna has a 1:1 swr at 2.390 mhz..... Good luck! Ken KG0WX |
