Beams

What makes our beams truely unique is the focus we have on ways and means of achieving light weight, strength and performance.  Light weight and strength are perhaps the two most important issues to deal with even before you commit to the time and effort to make sure a given antenna performs.  Without these two attributes, the antenna will most certianly not be around for the long term.

Consequently, we are attracted to the benefits of wire-based beam technology.  Wire is readily available, it is readily repaired and replaced. But perhaps more importantly, wire-based beams provide a very effective means of managing in-air weight.  In-air weight is pretty obviously, a determining factor in the longevity and cost of the overall antenna.

NuBeam

The NuBeam is an beam antenna designed to fit into restricted spaces. Where as the normal yagi is greater than half a wavelength wide, the NuBeam is sometimes lass than half this size again.  It is very light weight - a 10MHz NuBeam can be lifted by one arm.  The NuBeam provides an excellent balance of good performance, light weight and ease of installation and rotation.

5band-1xDE loop quad

The 5-band, 1xDE quad provides high levels of gain, often exceeding that of other similar quads. What makes this quad unique is that it uses a single DE for all 5 WARC bands and 5 reflectors. Then, we use a single shielded-balanced feedline for all frequencies. But the single DE is not a simple loop. It is phased loop feed so that its one wavelength on 20m, and 2 wavelengths on 10m.  The DE is derived from the Lazy-H antenna.  It is inherently multiband, and it performs with significant gain over simpler quad arrangements.

30 and 40m 2-element Beam

Dont we all wish for a 10MHz or a 7MHz beam! Trouble is, in reality, we find they are just too big. But they need not be. We make a 10MHz NuBeam (mono-band) a 7MHz NuBeam (mono-band) or, if you are really game, a duo-band 10 and 7MHz NuBeam. The 10MHz NuBeam is just 5m wide, the 7MHz NuBeam is just 7.2m wide.
 

Moxon Beams

Although the Moxon beam does not really fit our definition of restricted space antennas, it still has some very nice characteristics. Although it is slightly narrower than the standard yagi, its main feature is its high front-to-back ratio because of its closer element spacing.  Where we apply it is to the VHF and UHF sections of the ham bands.  We take 2 or 4 Moxon beams, mount them vertically, and back to back. What we achieve is a high performance 2 or 3 band base-station antenna for 6/2 and/or 70cm. Imagine,  four back-to-back  Moxon beams, each delivering 6dB gain, vertically polarized with 40dB f/b.
