SGC was formed in 1971 by Don Stoner and Pierre Goral. Both of these men brought extensive experience in design and construction of radio equipment. Don was known for his many publications in the field of ham radio, and Pierre had become a leading expert in getting top performance out of HF systems.
The company was originally called Stoner-Goral Communications, but that was soon shortened to SGC.
TENNADYNE has specialized in the design and manufacture of the broad-band Log-Periodic Dipole Array antenna, from 1.8 MHz to 3.0 GHZ, supplying these antennas to Commercial, Military and Amateur Radio (since 1990) interests worldwide. The Pakistan Army has exclusively used TENNADYNE Antennas for United Nations Peacekeeping Operations in Somalia, Bosnia, Haiti and Western Sahara.
SMC was established in 1958 and initially specialised in support masts, towers and the manufacture of antennas.
Today SMC is recognised as one of the most comprehensive and professional mobile communications companies in the UK covering the world market.
Between them the SMC group of companies can advise, design supply and install practically every form of mobile communications, from simple but robust radio systems, mast and antennas to the most sophisticated communications equipment designed for the 21st Century.
Antennas and Masts
Founded in 1958 as a private Limited Company to design and manufacture a range of HF antennas and Radio masts, together with associated accessories, SMC quickly developed into the Land Mobile Radio, Marine Radio and Amateur Radio fields, giving a very broad span of expertise in both the home market and particularly the overseas markets.
A brief resume of our current capabilities is as follows:
Masts
A full range of tubular support masts, for many applications from 6-30 m in aluminium, steel, and composite glass fibres, is designed and manufactured in house, with the added capability of customising to specific environments or applications.
Antennas
SMC specialises in the manufacture of HF communication antennas including simple dipoles and multifrequency trapped dipoles, wide band, low and medium power antennas, and we have the flexibility to produce 'one offs' for specific requirements. A small range of VHF antennas is also available.
Tactical/Transportable Antennas
For many years we have manufactured tactical and transportable military antennas, starting with the very popular LW8 Tactical dipole weighing less than 1kg, to a range of wide band, directional, and Omni directional, antennas for up to 1kW, specifically designed to cope with modem frequency agile equipment. Incorporated into the latest range of tactical antennas are modern high strength/low stretch materials such as Keviar and carbon fibre, giving tough, very light weight systems.
Special Antennas
Again our flexibility comes to the fore when we are asked for a design for a specific task, or, an existing design may require special treatment to suit special applications. If your requirement comes within our capabilities we would be happy to help.
