The XR4 - An 8 element multi-Band HF & 6m Super-compact Yagi covering 20m/15m/10m/6m bands with a single feed point

The XR4 was inspired by the C3 Force12 tribander. However, the XR4 has been given the 6m band in addition to the traditional HF 3 bands of 20/15/10. Furthermore it is much smaller than the C3, comes with a capacity loaded 20m element version (XR4C) which reduces the longest element from 11.6m to 8.9m) and reduced turning radius too! The XR4 is set toaltbecome a market-leader very quickly. Why not get ahead of the pack with this one and get your order in early!

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.
