which 4:1 Balun to use
 

Can anyone tell me what is the best 4:1 balun to use with a wire dipole
configuration a voltage or current balun?
I want to be able to tune with the FT-1000 MKV Field internal tuner.

Thanks

a 4:1 for a dipole?? all you need is a simple choke, especially if you are
going to have a tuner anyway.

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,

I thought you were using a real tuner. Having it work with a 1000MP internal
tuner seems optimistic. What's your SWR on 10m ?

From the ARRL Antenna Book, for a 3.5-30 mhz choke, coil a 10 foot
section of coax into 7 turns, and tape them together rope-style (this
is for rg-8, 58, 59, 8x or 213).
