I you could give me the exact dimensions I can model this. 140ft is quite large for BCB and I'd expect some possible pattern degradation for the upper BCB. What is the apex height and approximately how far above ground is the 140 ft base wire?
However, it is concerning that your nulls are great on LW, but poor on lower BCB. How are they on the upper BCB? You may wish to try to debug your setup with a fixed resistor and if you suspect any issues with the Mini-Circuits balun, use that home brew. 73 KAZ -----Original Message----- >From: Alan <[email protected]> >Sent: Oct 27, 2011 9:42 AM >To: IRCA Hard-Core <[email protected]> >Subject: [IRCA] KAZ Antenna Query and two TA Unids > >Hello guys, my first time posting to the list. > >First of all I am a KAZ fan, had great success with one a couple of >years ago, >well it was actually a "Super KAZ" with a longish base line of 140'. > >I re-erected this ant a few days ago, this time with remote termination >control >as per the (Mark Connelly, WA1ION ) design, using the Mini-Circuits >balun over a >home-brew model on the previous KAZ, and power feed down the coax. >Only difference form the published article is my use of 1mh chokes >instead of the stated 2.2mh, >all I had in the junk box ! > >I am getting a shallow NULL on the on the lower portion of of the MW band. >However I have a super NULL on LW, and can take out the strong162 from >France >which is where the NULL direction should be. > >Any help would be appreciated. > > >Log Query: >TA prop has been very poor from this side (Europe) of the Atlantic so >far this season. >Logged two unids on 650 & 820 this morning just after SR, both seemed to >be carrying >religious programming with no call id's during the very short time they were >audible, as is usual for these stations ! > > >Best Regards >Alan Doherty, GI0OTC ex GI8YDZ >Atlantic Coast of N.
