Constructive input needed::::::::::::::

 

Getting ready to put tower #2 in the air ---- 130 ft. ROHN 45G which will be
guyed with phillystran. 

The planned antennas are as follows:

 

1) MOSLEY MP-33N with 40 mtr. add on at 132 ft. -- rotatable

2) CUSHCRAFT A3S with 40 mtr. add on at 85 ft. --- fixed NW 

 

Plans are to add a stack match. 

Both antennas will be fed with 75 ohm hardline cut to proper length. Wire
antennas will also be located on this tower.  

Will there be some pattern distortion due to different antenna spec's? 

What are some problems that others have had in stacking two different
antennas such as these? 

Thanks
