I picked up a 1:1 balum at a local hamfest, i got it because it had a
N connector and thats the type of connector on my coax. After looking
closer i thought it was a 10-40 meter but i
cant make out the print, it may be 10-40mhz.
I desided to open the pvc to find out just what was inside, I found a
bunch of ferrite disk stacked over the coax, this wasent my idea of a
1:1 balum. I hoped to make a 160-10 meter
dipole/inverted vee using the proper length wire on each leg for
160,80,40 & 10. My question
is this, will this work at lower frequencys 160 & 80m ? If not what the
purpose of the ferrite
disks, it seems that i could just remove the disk if they limit the
frequency range, i guess
im trying to inderstand what makes this a balum & what purpose the disk
serve?
