Here's the lineup of aluminum, steel and copper as of November, 2005:
160 meters: 4 element vertial array (4 Square) using elevated radials at 16', Comtek combiner
80 m: 4 element vertial array (4 Square) using elevated radials at 10', Comtek combiner, relays for CW/SSB switching.
Two 2 element delta loop arrays for four directions, horizontally polarized, from catenaries between towers at ~110'. Relay control of direction and CW/SSB switching.
40m: Two stacked 4L M2 yagis at 135' and 65'.
4 element vertial array (4 Square) using elevated radials at 10', Comtek combiner
2 element Cushcraft yagi at 110', fixed at 100d.
20m: Three 5 element KLM (42' boom), modified to W6NL design, at 135/90/45'.
15m: Three 6 L KLM (37' boom), at 135/90/45'.
10m: Three Hy-gain 105CA (modified to W6NL design, at 108/54/27'. Mount at 81' awaiting the fourth antenna.
All towers are Rohn 45, rotators are T2X (15/10m), RD-1800s (20m), Alpha-Spids (40m).
4 SQUARE ARRAYS are all made of wire, suspended from Dacron rope catenaries from three of the towers. Radials are supported by 4x4 posts with PVC pipe extensions. Details on the 160m array and construction are in a 1999 NCJ article (I'll find the exact issue and revise this, or post a .pdf)
Three beverages for 160/80: to JA - 800'; EU - 500'; E-W reversible 550'.
135' tower with two 40m beams, and if you look carefully, a two element loop array for 80m.
