VHF/UHF Amplifiers

With over 30 years experience in building VHF and UHF amplifiers our current amplifiers continue to demonstrate our commitment to suppling top quality, hand built, rugged units that will give many years of hard working service.


Gemini HF-1K  the all new 1kW output solid state HF amplifier covering 460KHz-50MHz.

Gemini 4,2,70,23 - A range of solid state 300W (200W on 23) linear amplifiers built on an all aluminium chassis with integral linear power supply for 6m to 23cms.


The amplifiers are built on a CNC cut and folded steel chassis that is rigid and hard wearing. The front panel is bolted directly to the front of the chassis for total rigidity.

Our high performance UK manufactured toroidal transformer is bolted straight to the chassis using a strengthened support to allow transportation without risk of damage.

Valves used are either GS35B, GS31 or 8877 depeding on model and customers request.

Solid brass stripline or Pi-L anode lines are used - silver plated to ensure minimal surface losses and long term stable perforamance without the need for retuning.

All amplifiers are designed and hand crafted here in the UK using locally sourced materials wherever possible and come with a 1 year warranty on the tube/rf device and a TWO YEAR WARRANTY on the amplifier.

Every amplifier is hand tested on every band and burnt in overnight to ensure it leaves here ready to perform and keep performing.
