Closed loop antennas are always less sensitive to noise than open driven element antennas (e.g. vertical or dipole).  This Multiband Delta Loop antenna, designed by M0PLK, has a unique configuration and feed solution resulting in low angle radiation, thus making it a great performer on real DX.

The antenna has been the subject of technical articles in a number of HAM RADIO magazines (e.g. Poland, Russia, Ukraine) but was rejected by the UK's RadCom because its description was already on the PDXA web site.  After waiting 3 months for RadCom's Technical Department to acknowledge our submission, we decided to put it on the www for everyone to see.

 

• Performs well on 30-20-15-12-10m.
• Usable on lower and higher bands with reduced performance.
• Low radiation angle due to novel top-feed system using low loss ladder line.
• Based on the Multibander 7PL antenna.
• Bi-directional and very low noise in comparison to a vertical.
• Design is non-resonant so an ATU is required.
• Comes complete with ladder line, main loop wire, aluminium telescopic rods, matching transformer. No guying system and assembly instruction (very simple and partly pre-assembled) is included.
• Available with aluminium rods instead of composites, ask for details about version FG or ALS.
