I'm looking for recommendations and rough costing info (from
experienced owners of the make/model they tout) on non-crank-up (fixed) self-supporting (un-guyed) towers . (I would *consider* buying an excellent condition used tower within 100 miles or so radius of Allentown, PA, but I'm thinking primarily about buying a new tower. I have no ht. restrictions where I live and want to move on this before winter sets in, so I need to make a decision and act ASAP.) I'm looking at the range of 55'-75' ish, depending on several factors: 1) cost vs. height and wind loading (looking to put a "large" (6-9 element?) 6m beam just above the top of the tower, with a 2m/70cm/? satellite array above that, and a PD-220 "SuperStationmaster" side mounted with the tip near the top ... and almost certainly some other small VHF/UHF antennas side-mounted at various locations ... but the latter will not contribute significantly to wind loading as they will be very modest) 2) code here requires 90 mph wind survival rating 3) I have space for a foundation base up to the 5'x5' range by, say 6' deep. Actually, I have 12 acres, but where this tower will go, next to the house between some windows, I want to limit the size to 5'x5' if at all possible (it's rocky here and digging that hole will be a SOB ... I'll almost certainly look to have it dug by someone with a machine ...) 4) a HD rotor must fit inside the top section, with a top plate for thrust bearing available to handle vertical loads ... 5) Within cost constraints, there is no such thing as "too heavy-duty." Any help, please? 73, Carl - wk3c |
