All,
As many of you have read and are probably tired of hearing, I am chasing down
my RF ingress issues into my Flex 5000a, which seem to be even acting up on 40
meters and above now.
As part of my potential solution, I will be purchasing a isolation choke. I had
decided on a product, when a friend of mine pointed to another product that is
almost 1/3 the cost. Now I do believe in the old adage that you get what you
pay for.
I was on the phone with Bob from Balun Designs. He suggested a dual core
1115DU. The cost is $79.00 plus shipping. The item has great characteristics as
far as SWR, line loss and choking impedance from 160-10 meters.
My friend in a QSO last night suggested the MFJ-915. This item is only 29.99.
It consists of a bunch of ferrite beads. As it is MFJ, I do not expect them to
publish any specifications or sweeps from a spectrum analyzer.
Hs anyone dealt with either one of these products or both? Can you give me your
honest opinion on the performance versus cost analysis?
Thank you and 73
Robert
