MACO 107 C Antenna: Gain & Performance Analysis

What can we expect from the STOCK MACO 107 C

 

An analysis of the antenna using EZNEC PRO4 with NEC 4 NEC5 engines.

 

In order to keep it fair to all others:

• We did  not implement losses due to material or matchingsystems

(peak gain should be fraction less if measured in the real world.)

 

The sizes we used are from the onine manual at MACO :

 

 

 

 

We used the sizes for 27,205 MHz

The MACO 107 C dimensions  implemented in EZNEC :

 

 

 

 

 

 

Above the freespace azimuth plot for the MACO 107 C

 

Above the freespace elevation plot for the MACO 107 C

 

 

Above various azimuth plots verus frequency

 

Above the gain / front to back / front to rear response verus frequency

 

 

Above the SWR response with the antenna matched to 50 OHms.
