Mini Quad Beam


Looks to be quarter wave size with the hats presumably lengthen the elements. Wonder if Marconi has plotted one like this?

Have specks for a 2 element cubical quad in quarter wave. But needs to have section of 75 Ohm coax at the feed point. There is some math needed, but you can tune impedance by adjusting element length and element spacing. Tedious. I went and bought the L2 cubical quad today.

Just looked at the specs on your L2.
Nice! (y)

We'll see. Just didn't want to spend time and about the same in money to build. The L2 is full wave 50 Ohm. The quarter wave I modeled/ spec'd out is doable but a real bitch to tune. Didn't have cap hats in mix. Not sure if those would work.

The one you pictured looked to be about 5 foot boom length, and elements to be quarter wave.
 
Moxon is nice. One in wire would be less wind drag. Thought about build for that, but we get good wind here just north of Corpus. Didn't figure it would hold up.
 
using a Antennacraft Rotor,and I'm only up 22 ft Horz in McLendon-Chisholm Tx
Just looking for that rotator and seems to have hit unobtainium status. Antennacraft is out of bidness. Ordered the RCA from Amazon. I'm sure it wont impress me.

I have 30' breakover, drillpipe Redbeard Special, reluctant to take my StarBuster off it. May try to mount the quad with the StarBuster on top. Not sure if the later would create interference having the mast higher than the quad beam.
 
Sent a e-mail to the man that has it, this is what he said . It,s a 11 meter beam 500 watts / 1200pep...4.5dbd gain...1:1.5 SWR....12db side rejection ...25db front to back ratio that all I got from him. Hope it helps
