changed my mind about avanti antennas? no eddie,
though i do think they were guilty of trying to pull the wool over our eyes with their claims about prior art antennas,
the sigma4 does provide more signal at low angles than any 5/8wave when mounted on the same pole, for me the adjusted vector does even better but the vector build quality is poor,
it looks likely it may not do it as i first imagined and for sure the increased height of current maxima is a vital part of the equation,
i still don't know exactly why i can manipulate signals or why a monopole length part way between the original sigma and original vector works best in our tests,
all that bs about lossy gammas and higher takeoff angle than a 5/8wave was and still is technobull,
i picked up my astroplane this evening, a Big THANK YOU 
to Henry and mark, if it had not been for those guys i doubt any of us would have got our antennas,
i have not opened the box yet, it looks good sat beside my NOS avanti saturn,
takes me back to when i was a lad opening my first sigma4 & assembling it in my mums room ,
then realising i had to take it apart again to get it outside,
i will let you know what i think of the astroplane when i get it or my homebrew up in the air at the same tip height as the i-10k on the same pole same coax,
It ain't over till the fat lady sings
thanks for doing the astro models,
can you put the cursor on the lower lobe or does it always go on the highest gain lobe in EZNEC ?.
