Topband: MFJ-1026

[Jacques RAMBAUD]

Hello,
just finished to rebuilt my two wires 250 m beverage .
>From the feed point I have two coaxial cables arriving to the shack, I was considering to built a switch to go from one direction to the other and maybe also add an MFJ -1026 phasing box to do some null-steering or improve noise  cancellation.
I have two questions :
-is it worth the effort ??
-I measured the ports impedance of the MFJ-1026 and found that VSWR is really bad , like to know if somebody has made modifications to that equipment to improve it ?
Thanks
