Element Placement - Hy-Gain OSCAR Ant's

[KE7WVZ]

Does anyone know what the Element Spacing (on boom) is for the Hy-Gain OSCAR VHF/UHF Antennas ?

These antennas are :
DB-218SAT....package of both 2m & 440 MHz Ant
VB-216SAT....2m
VB-7030SAT...440 MHz

I'm trying to homebrew 2m/440 MHz antennas from these designs.  I downloaded the manuals however, the manual does not show spacing of the elements on the boom.
{ manual does show element length(s) }

also...anyone know what the actual switching circuits are in the phasing/coax assembly for these antennas ?


Thx

Hi Dirk,
Try using the Cushcraft A-144-20T yagi, all you have to do is move one set of elements a 1/4 ahead of the others. I have done this and it works well. The other 435 antenna I have is a homebrew 10+10 which is RHCP. I can send you all the dimensions if you want, email me direct. The M2 436CP30 yagi is another way to go. At this time I have 5+5 on 2 meters for the downlink and 10+10 for the uplink and I can start hitting the birds as soon as the outer ring comes into view from my QTH.
