In looking at various antenna designs and many DIY ideas, I have come back to the idea of the Spiderbeam. As in other threads, I would like to make my own antenna. In consideration of this, has anyone built a Spiderbeam without buying the kit? I've compared spreaders in another thread: http://forums.qrz.com/showthread.php?327590-Spreaders-Spiderbeam-vs-MaxGain-Type-1-which-is-stronger I think the MaxGain Type 1 spreaders would be stronger and less expensive. This is what I have found so far in terms of a DIY, 5-band spiderbeam: rope & wire --------------------- 47 + 15m = 62m kevlar used for guying the spiders: ~ $37 82 + 22m = 104m dacron used to support wire elements: ~ $41 73 + 30m = 103m of wireman cq-532: ~ $64 spreaders --------------------- 4 type 1 spreaders from max gain: ~ $100 spider --------------------- 1 spider - cast, custom, or Cubex: ~ $60 This comes to around $300 not counting shipping or other parts such as clamps, bolts, etc. Call it $400 shipped. In contrast, the commercial kit would cost around $650 shipped. One could save about $30 by using different wire, such as (http://www.homedepot.com/Electrical...splay?langId=-1&storeId=10051&catalogId=10053) and around $80 if using (gasp) PVC pipe. The use of PVC is generally discouraged for spreader use but PVC does have some good points. It's cheap and easy to replace. It's easier to work with as well. You can replace your PVC spreaders probably 4 times before you've spent the same amount on PVC as you would have on fiberglass. And by the second or third time, I think you would have the weaknesses worked out to where you could prevent future problems. If you have a crank-up tower, the maintenance/replacement issue is far less of a problem and might even be considered to be a non-issue. Unlike when using fiberglass spreaders, the guy system would have to take most of the weight of the spreaders because fiberglass spreaders can support themselves to a point but PVC would sag too much. However, the Kevlar rope should do the trick. One would also just add more guy points. Also, in the Spiderbeam design, you can keep the spreaders horizontal if you want. In contrast, the hexbeam design stresses the spreaders upwards and PVC really sags. I think it would be much harder to maintain hexbeam geometry with PVC than to maintain the horizontal geometry of the Spiderbeam with PVC. I have conversed with some hams who have used a PVC hex design with some success. Breaking doesn't seem to be the problem (due to high flexibility) but sagging is a major problem. This could be dealt with much better on a Spiderbeam. Nevertheless, a $400 dollar DIY Spiderbeam that uses the MaxGain Type 1 spreaders sounds interesting to me. What do you guys think?
