In general, it can be said that higher frequency (40 meters and above) arrays must use the

smaller spacing to maintain good RDF and acceptable pattern. Also, in general it can be said

that the RDF is greater when the Eznec front to side lobe ratio nears -13 dB which is a really

noticeable ratio. It can also be said that as the array size gets smaller the array output level

decreases. All these plots assume no adverse effects from physical real estate issues

dictating array size or objects close to the array.

It is our recommendation to use the recommended 60 foot side dimension with a 60 degree

long delay and 30 degree short delay cable or the 80 foot side dimension with the 80 degree

long delay cable and 40 degree short delay cable.

60 foot per side 60,30 Phase cables

80 foot per side 80,40 Phase cables

Very similar patterns at 160 Meters with 60 or 80 foot side dimensions.
