MACO 104 C

What can we expect from the STOCK MACO 104 C

 

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

 

In order to keep it fair to all others:

  • We didĀ  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 :

 

 

It is worth to mention: Although the 3el yagi has specific sizes for different frequencies, the 4 elements MACO comes with just “one size”.

The MACO 104 C dimensionsĀ  implemented in EZNEC :

Above the freespace azimuth plot for the MACO 104C @ 27,555 MHz

 

 

Above the azimuth plot comparisment for different frequencies.

 

 

Above the SWR plot (WITH A GAMMA-MATCH to for adjustment)

 

 

 

Above the gain and front to back / front to rear respons versus frequency.
