Message 1 of 7 , Apr 30, 2012
New to the group, I am thinking of building a small model for 10 or 6M
to get my feet wet. I'm looking at using driveway markers (I've seen
the W3BEL design for 6M), bicycle flag poles (I can get those in 5-6ft
length), or possibly 48" chimney sweep poles I saw in a local big-box
home improvement store (they have threaded ends to extend them and are
reasonably stiff). I've been reading design info in the files section
and searching the list archive - haven't seen a discussion on spreader
length as a function of lowest operating frequency.

For a broadband (M-W) design, is the spreader length a few inches (or
cm) more than 1/2 the driven element length? Looking at diagrams of
hex beams, it appears about 1/2 of each driven element wire runs out
the spreader, then the balance bends back towards the reflector. The
spreader needs to be a bit longer if an upward bow is required.

Is there a simple (or not so simple) formula, or should I sketch out
the geometry and see how much high school trig I remember? Pointers
to appropriate files, websites, threads on this list if this topic has
been answered and I simply missed it.

If you order the spreaders from www.mgs4u.com you get the center post material also. They have parts and/or kits.
I am also just starting mine, about all I got done was to cut out the base plate and scrounge up some P clamps for the tips.

Message 7 of 7 , May 17 11:38 PM
Steve,
I used crappy fishing poles from "Game on Fishing" as spreaders for my 15m band monobander. They are 3m long but the top part is rather thin and might not be suitable for 20m band hexbeams. I have a video on the construction and first QSO (12000km dx) proving that is does work!
Search for PA3DSB and Hexbeam on youtube.

Good luck,
Paul PA3DSB
