[Antennas] Half square

[r miles]

I use one on 80m. Cebik design. Fed in  upper corner with 50 ohm coax. 
Cebik said folding the vertical legs  inward has little effect. Mine is 
only 40' high & the bent inward  vertical element ends are only 6' off 
the ground. So I can mow under it. SWR is good for 100kc without a 
tuner. I  have never ran any tests other than the MFJ  analz.  to cut it 
for CW.
All I have is on air performance. I  chase DX &  it seems to have a low 
take off for such a low antenna. In last weeks CQ WW I  was on 16 hr.s 
on 80m. 500w & a K3. Just hunt & pounce. 177 Qs , 87 countries and 22 
zones. It has a 200' feed line too.
I see no reason  the design  wouldn't be good on 30m & 40m. I use a 
Cebik design 2 ele Moxon yagi on 30m.
It  didn't beat the 4 squares & full  verticals but most every thing I 
called I got thru quickly. It seems omni directional but there is a 
small  bit of gain broadside. It's not a scientific  analysis just  an 
on air evaluation.
