yagi 14 meter

A 5 elements Vee log-yagi for 10m - 5 elements "vee" log-yagi for 10m band- boom lenght : 4mt. Gain : over 10 dBd , f/b =over 40 db (deep null) f/b= min 20dB for different polarization signals

2 Meter 10 Element Quagi Antenna - This antenna was designed by N6JSX Kuby for Transmitter hiding. Fitting the requirements of directionality, high gain, and portability. This antenna was derived from the ARRL Handbook information on Quagi's and Yagi's; in the absence of two meter Quagi information, UHF Quagi dimensions were scaled into 146 MHz use.
