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 .

VO1MP

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.
