[TowerTalk] W2AU Baluns??

[Tom_N2SR]

The last Radio Works unit I had, I was using on my 80m vertical.   Was supposed to only be temporary, but you know how that goes sometimes.  Was trying to work VK0EK the first night, and the VSWR would rise and the Acom would trip out after a few calls.  
Saturday morning I lowered the vertical, used a modified Budwig center insulator (drilled some holes for strain relief) to reconnect the vertical, attached the coax, and then put about 8 split ferrite cores around the coax.  Taped them in place, then taped over them to weather proof them.  These are the ones that are about 1 inch square, with a 1/2" hole in the middle.   
Saturday evening, I worked VK0EK on 80cw in 20 minutes.  No reflected power issues.  
Ordered a Balun Designs balun on Monday, which has been in use on the antenna since then.  
Opened up the Radio Works "balun,"  Mine didn't seem to have RG-58, but some sort of "shielded wire," with a white dielectric.   As you said, probably 40-50 very small beads that went over the shielded wire.   Entire assembly was pushed into a piece of 1.5" white PVC.

And similar to issues I have had with Radioworks "baluns." ??

##  radio works has no clue how to build a balun.  Dunno if they are
still in business or not,  firefox sez their site is bad news and  I cant get to it
anyway.  radio works used a piece of  58-U with a few beads on the coax,
wrong beads, loads of bad soldering, water ingress, you name it.  Then 
they had the audacity to rate it for 1.5 kw CCS  RTTY.  



##  balun designs seems to have it figured out...as does    Myantennas.com
