[Hi-zreceivingarraydiscussions] DIRECTIVITIY 8 CIRCLE

[k4pi at bellsouth.net]

I have an 8 circle in 200 ft diameter.  I notice the F/B and F/S are mainly only good on 160.  Even on the upper portion of the BC band for the most part the F/B is not great.  Not that I need this but I have used Hi Z 4 squares with 90 ft on a side and they seem to have good F/B on the BC band and other bands.  On 80 with the 8 circle I can tell the most predominant direction of a station but there is little F/B and F/S.  Just wondering if this is what others are seeing.  It receives fine.  

I am well pleased with the system but just wondered what others were seeing.  I am using only a single 4 ft ground rod and wondered if anyone else had seen any improvement of the system with more ground rods.  Also wondered if anyone else was using common mode chokes in the feed line as recommended by ON4UN’s Low Band DXing book.  I have one at the receiver end built from K9YC data.  My feedline is about 450 ft long being cable TV hardline.  It is grounded once in the middle.

Would like to hear from others on their experience.
