The Force12 XR3 - A 6 element tribander HF Super-compact Contest Yagi covering  the 20m/15m/10m bands with a single feed point

The XR3 tri-bander was inspired by the C3 Force12 tribander providing the traditional HF 3 bands of 20m/15m/10m. Furthermore it is much smaller than the C3, comes with a capacity loaded 20m element altoptions (XR3C which reduces the longest element from 11.6m to 8.9m) and reduced turning radius too! The XR3 is set to become a market-leader very quickly, why not be ahead of the pack with this one and get your order in early!



20m Band

Gain: 6.1dBi

10m Band

Gain: 6.78dBi

F/B: 21.78dB

SWR coverage: Better than 1.5:1 from 28-28.6Mhz without an ATU or re-tuning 1.9:1 SWR up to 28.7Mhz

2+ active elements


Power Rating: 5kw

Boom Length: 3.1 Metres

Weight: 20Kg

Turning Radius: 5.28 Metres

Wind Loading: 0.8 Square Metres

Wind Survival: up to 201KPH / 125MPH

Other options available if higher wind loading/survival is required.

Stacking Distance: 7 - 12m ( 11m recommended)



The boom is made from 45mm diameter square tube with a wall thickness of 3.2mm and thus is super-rigid. The largest diameter elements are the 20m elements which are 32mm diameter in the centre (with 3.2mm wall) tapering quickly to 9.5mm. Marine grade stainless steel is used throughout our antennas.  No guying or boom truss is needed with this antenna.

Our antennas are constructed with the best quality materials in order that the best mechanical construction can be achieved, not the cheapest and most profitable!

Note: Much development time has gone into our antennas, not just on basic electromagnetic design, we are able to model the effect of insulators, booms and other objects to ensure the make up of our antennas have least effect on performance and pattern degradation.
