D & A Holmes Pty Ltd, trading as WINSIG Antenna Systems
​ABN 68 609 740 990
Staffed by Professional Engineers, with over 50 years of combined experience, our goal is to seek out practical solutions for Television reception issues for mobile homes and caravans.  As caravan enthusiasts ourselves, we are well aware of the limitations of some existing antenna installations, from our travels throught Australia. 
​Our products are proudly manufactured in Melbourne.

We do not have a retail site, as we seek to keep our overheads to a minimum.  This means lower prices to our customers. 

All of our products are designed using the latest Computer Aided Design and Analysis techniques from Solidworks.  We develop and test our products extensively in both the laboratory (such as the Swinburne University Radio Frequency Laboratory - shown above), and in the real world throughout Australia.

Successful test locations in Australia for Winsig Antenna Systems.
