301. [TowerTalk] Aluminum elbows ?? (score: 1)
Author: cebik@utkux.utcc.utk.edu (L. B. Cebik)
Date: Fri, 9 May 1997 06:47:05 -0400 (EDT)
Are there any such things as aluminum elbows (similar in construction to the copper pipe elbows used in plumbing)? IF there are, I need 4 for corners of an experimental antenna using 1" OD al tubing.

I have added just a few notes and 1 graphic to the EDZ Update notes at the site. They are unimportant practically, unless you are curious about how you might make a non-Yagi beam with 21 dBi forward

John, Your question has general interest, so I'll post my notes to you. Hats need never be perpendicular to ground. They work on the ends of dipoles at 90-degrees to ground; I have constructed 2-ele

A better comparison for the announced beam might be the idealized 3-element beam I have used for some comparisons, with a max gain in the region of 8 dBi (free space). Comparing 2 and 3 element beams
