Made to meet our exacting specifications, our GNSS antennas receive signals on the L1, L2, and L5 satellite bands enabling our equipment to receive signals from the following satellite constellations' high precision secondary data transmission band alongside the standard accuracy (L1) band.
- GPS (USA)
- Galileo (EU)
- GLONASS (Russian Federation)
- BeiDou (People’s Republic of China)
Our GNSS antenna is manufactured using Brass and does not require a steel ground plane which makes them sutable for use with Magnetic Gradiometers. Please contact us for further details.
RM Frobisher (1986) Ltd aren't standing still! We have a policy of continuous research and development to make modern, reliable equipment available to individuals, professional archaeologists, and groups and societies.
Our current development project are spiked wheels to replace the probes attached to the TAR-3's frame to allow the user to push the frame and take readings without the need to lift the probes clear of the ground. The wheels measure the distance moved and the TAR-3 records the measured resistance every 0.25m (four readings per metre) The user can walk at up to five miles per hour (8 kph, 2.25ms-1) and stop and start while taking readings.
‘The TAR-3's wheels will make resistance measurements as faster than magnetic gradiometry!’
The TAR-3 spiked wheels will be available soon! Please contact us if you would like more information.

New Products
While we can’t make site visits we are busy developing new products and adding new features to our existing products. Not being able to visit some of our suppliers is delaying some aspects of our product development but we are working on other areas.
New Products in Progress
Before products can be placed on sale they require fittings, enclosures and other parts to be manufactured. These brackets have been laser cut and formed into shape. They are being sent out for 'tumbling' to de-burr them before being power coated. These final operations enable us to produce high quality products.
Like all of our products, new products are supplied with all of the parts, accessories and tools needed to use them as soon as you unpack them!
