YAGI DESIGN INFORMATION
All Hf Yagi Antennae were designed and built by VO1MP and use Mosley Hardware ,
This Hardware is durable and simple and I have found it is the only mounting hardware that
survives a typical Newfoundland winter .
Lots of Wind and freezing rain .
OWA = Optimized Wideband Antenna
Considerable work has been done on OWA designed yagi antenna systems, the link below provides some of the dimensions and performance data recorded by WA3FET and his team experimenting with these designs. In this case the design was optimized for gain and performance and in most cases resulted in much longer boom lengths. In my case all efforts were expended to achieve optimum results utilizing as short a boom length as possible to achieve gain and bandwidth. Consequently these antennae are easier to handle and erect on smaller tower/support structures.
These designs demonstrated the same characteristics as their big brothers. Experimentation , using commercially available mounting hardware , led me to Mosley Boom to element clamps and brackets with fewer moving parts . This mounting unit is a single cast mount supported by a single stainless U-Bolt and is virtually indestructible.
These antennae were computer modelled and originally designed using a simple DOS based YAGIMAX FREEWARE program written by Lou Gordon K4VX. Unfortunately the program has never been updated to the new windows platforms and for a long time I kept a dos based machine available for this work. Performance features were verified by EZNEC and the Yagimax computer design results were confirmed as being very accurate.
Over the years the performance by these antennae has been outstanding. OWA designs are directly fed with coax and eliminate the losses generated by feed point matching devices. Co-incidental to the time these designs were originally published , desk top computers and antenna modelling software had become an affordale acquisition for most amateurs. Consequently, experimentation and design of similar antenna types was being simultaneously carried out by many Amateurs around the world. Several amateur antenna experimenters had developped similar designs. For a look at Breakalls's OWA designs I have provided a link below. These antennae designs have been used at several record setting /breaking contest stations in the US .

Some things about me .... trivial or other wise
As station operator Gus , I have been continuously active on HF since the late 1970s and like CW, Contesting , Dxing and the occasional Ragchew. A significant part of my hobby activity has been devoted to building , designing and on air testing of my HF antenna systems.
As a sometime dxpeditionner I have also operated as VO2CQ -Zone 2 , FP/VO1MP , VP9/VO1MP, W4/VO1MP, G0/VO1MP, CY9CF, VO1XX, J79MP, VO1MP/VE7, J75A. My other Canadian Calls are VO1XX and VO2CQ.
I have also been involved in local Amateur Affairs both Administratively and with Emergency Communications as :
A Past President of SONRA - The Society of Newfounland Radio Amateurs
The Founding and Past President of AVRAC - Avalon Radio Amateur Club , Providing Emergency Volunteer Communications for The Canadian Red Cross.
Amateur Radio Memberships:
RAC - Radio Amateurs of Canada
QCWA - Quarter Century Wireless Association
CWOPS - THE CW Operators Club
Honorary Member FCG - Florida Contest Group
