Since a normal half-wave dipole is approximately 70 ohms, or so, a standard 1:1 balun should do fine. Make sure it's a current balun (MFJ, Radio Works sells them).

Thanks. I have a MFJ-915 that I can install inline. MFJ says that I can use that or wire a air core rf choke. I'll have to find out what diameter and how many turns. I'm using 8x coax with a .77 vf.

Nope, that MFJ-915 is a line isolator, and won't do the job. Same for those coax chokes. Those are simple common mode chokes and are not baluns. I recommend the MFJ-918 for your dipole application.
Thanks. The dipole mount has a SO-239 connection point on it. I would upload the photo of it but MFJ restricts people from using their images. Here's the link with the pic and description

MFJ reviews:looks like you can build a set of beams out of the dipole mounts by using two or more dipole mounts

Never mind the negative ones.
You can use fiberglass antenna sticks tuned for different lengths and not just the venerable 102" stainless steel whip either. MFJ sells a stainless steel 108" whip as well

Hmmm.... OK. You really don't need a balun, unless you're anal retentive about balance and perfect patterns. With that gizmo, I wouldn't worry about a balun. Yup, run that MFJ-915 in line, and it should be OK.
My question is:do they make make a balun for this but since it's a balanced to balanced as long as the antenna elements are tune for the right freq center,...
The center of 11 meters comes to 8.66 feet for each dipole element.
The MFJ-259/269B is indispensable. I have one, and could not do antenna work without it.
Looks like they have them

This radio is not worth buying until the defects are addressed.
I should've put a disclaimer in. If you use the CW,it's too slow, talkback needs fixed so that it turns completely off. Otherwise it's a nice radio for phone communications.
