Information for the all band ocf dipole is on
the products and prices page.
updated July 2008
Kit Version of the All Band OCF Dipole.
The Products we manufacture are based on proven designs that we use ourselves.
We manufacture long wire baluns for enhanced Short Wave reception.
These baluns can be used for transmitting (100W) and can be used to feed the vertical section of an original Windom (1930's) antenna against ground.
We now have designed a 2kw version of the Long Wire Balun for feeding a Windom or various long wire lengths.
Our open magnetic path Baluns have next to no loss and can handle up to 5KW.
We currently manufacture 500W, 800W, 1.5KW, 5KW and 10KW baluns.
We use the best quality Australian copper in all our Baluns, even some of the ferrites used in our Baluns are made in Australia.
We manufacture OCF (Off-Centre-Feed) dipoles that will cover up to seven amateur bands.
One dipole that will cover the most popular amateur bands and no need to use an antenna tuner in more than 90% of installations.
The balun we manufacture for our All Band Antenna is a two stage open magnetic path design that covers the from 3.5Mhz to 30Mhz with less that .04 of a Db loss.
This balun is in my opinion has the lowest loss of any 3.5 to 30 Mhz balun on the market.
This is one part of our workshop, many interesting communications devices have been tested here, We have just bought a RF network analyzer that goes to 26.5 Ghz and a HP digital 21Ghz Spectrum analyzer.
This is only one small part of the operation, we have
designed such things as ferrite Baluns, microwave frequency converters, satellite antenna and sub systems, switchmode power supplies, microwave amplifiers for micro satellite projects, Doppler modules for 24 and 34 Ghz and Antenna systems.
