Re: [IRCA] CO TP Report 10/22/18

[Neil Kazaross <neilkaz58@xxxxxxxxx>]

Your proposed small DKAZ should work well in the upper part of the band,
but you won't have enough signal at the low end and I've and others have
experienced difficulties getting really good low band F/B with small DKAZ.
Based on experience I would not feel comfortable with much less than 20 x
84 ft, so if you can get some taller masts try that.  73 KAZ
