The XR4 MkII - The InnovAntennas XR4 - An 8 element multi-band 20m, 15m, 10m and 6m Super-compact Yagi with a single feed point.

The XR4C uses capacity to reduce the width of the 20m elements which is the most efficient method of loading Additionally, width has not been reduced more than 23% of the original radiator length, after this point radiating efficiency drops drastically.

The XR4 MkII has no matching devices, no traps, no coils, no hairpins so nothing to lose valueable power and thus, nothing to over-heat through these inefficient devices.

The XR4 MkII is an ideal partner for today's top SDR radios. There is no limitation in how many bands you can monitor or use at once. This means with products such as the Flex 6700, all 6 bands can be monitored at the same time.

The XR4 MKII has been in development for the last 12 months improving bandwidth and gain to ensure more of each band than ever before can be used without the requirement of an ATU

The more bands there are added to a multi-band Yagi, the more interlaced elements there are and in turn, performance per band drops with each no band added. The Unique design of the XR4 MkII means no more than 3 band are interlaced on any part of the boom.

The XR4 MkII is very forgiving in all weathers allowing you to enjoy your hobby whatever the location or time of year.
