HF Collinear Array Antenna 20m Band

The classic Collinear Array consisting of two ½ wave radiators in phase is an antenna  that  exhibits  some  degree  of  gain  (~1.6  -1.8  dB),  and  delivers  better  than  average transmitted signals even when installed at only ~¼ wavelength above ground, and is directly-fed with any length of 50-Ohm coax. SO 239.

The classic Collinear Array consisting of two ½ wave radiators in phase is an antenna  that  exhibits  some  degree  of  gain  (~1.6  -1.8  dB),  and  delivers  better  than  average transmitted signals even when installed at only ~¼ wavelength above ground, and is directly-fed with any length of 50-Ohm coax.  A further consideration is that this antenna is also quiet, when compared to inverted ?V?s? (and verticals,  especially).    A  reduction of 2 ? 3 ?S? units of noise may make the difference in that DX contact you can now hear above the noise!   And, the modest gain the antenna exhibits might also make the difference in whether that station also  hears  you.    Only  1.5  dB  of  gain  increases  your  effective  radiated  power  by  half-again  as much;  from  100  watts  to  150  watts,  for  example.    Capture  area  is  another  factor  in  the  good performance  of  the  array;  the  WA-CD20M  has  twice  the  capture  area  of  a  doublet,  or  inverted vee-type ?droopy doublet.?

This classic high-performance antenna give you a powerful, booming signal and needs just two trees  or masts to hang and play!

We have updated them with stronger, more durable modern materials, adapted some to simple, direct coax feed and made them hang and play.
Two Element Arrays
These WA-CD20M single band two half-wave element collinear array gives you nearly 2 dB gain -- about 150% power gain -- and twice the receiving capture area of a half-wave dipole. They have direct coax feed and low SWR across the entire band.
Built to last with high quality materials. Every antenna is tested before leaving and a report is printed with the antenna.

Hang and Play!
