Jack Belrose, VE2CV, wrote a series of articles for QST over 10 years ago, analysing the OCF dipole, and designin; /archives//html/Towertalk/2005-10/msg00554.html (7,655 bytes)

A current balun is always useful as an "un-un", but an "un-un" is not always a useful current balun. Some un-uns have no common mode isola; /archives//html/Towertalk/2005-10/msg00555.html (8,487 bytes)
3. Re: [TowerTalk] OCF dipole (score: 1): Author: jimjarvis@comcast.net; Date: Sun, 16 Oct 2005 16:11:10 +0000; Yup...complete agreement, Tom. The line isolators will give you a couple hundred ohms, at best. My solution...and it's a seriously compromised one...is to use clip-ons which are 2x the amount of what; /archives//html/Towertalk/2005-10/msg00557.html (10,594 bytes)

They have many merits, and some demerits, which you can read on W8JI's site, or in the white paper on the Yankee Clipper Contest Club website; /archives//html/Towertalk/2007-10/msg00877.html (8,088 bytes)

Re: [TowerTalk] OCF dipole (score: 1): Author: "Scott McClements" <kc2pih@gmail.com>; Date: Wed, 31 Oct 2007 10:44:09 -0400; It is not necessarily true that a tuner will be required, except for on the 15 meter band. I am personally running the Buckmaster OCF dipole, which they claim uses a 6:1 balun of a non-descript type.; /archives//html/Towertalk/2007-10/msg00886.html (7,343 bytes)

What exactly does unbalanced mean in the context of the OCF feedline? The Zepp, which has worked honorably for years, must be as u; /archives//html/Towertalk/2016-12/msg00166.html (7,726 bytes)

Both the writing and slides for the talks are on my website, so I won't repeat them here. If you care about the answer, read them. What; /archives//html/Towertalk/2016-12/msg00167.html (8,488 bytes)

Funny that you'd think those who don't like the OCF design would instead be touting "commercial stuff with funny matching devices and impressive names." Home-made dipole, home-made choke.

The OCF dipole has a varying pattern with deep nulls on some bands and it's difficult to choke. However it loads on multiple bands and you can work some stations with i; /archives//html/Towertalk/2016-12/msg00180.html (8,970 bytes)
