PST-RD40S - ROTARY DIPOLE FOR THE 40 METER BAND - LINEAR LOADING SYSTEM - TOTAL LENGTH: 14.5 m

TECHNICAL DATA:

• Impedance = 50 ohms
• Front-to-side ratio = about 15 dB
• S.W.R. = see graph
• Length = approximately 14.5 m
• Rotation radius: about 7.30 m
• Weight: about 8 kg
• Mast attachment: 48-50 mm standard - Pre-drilled holes also for 60 mm mast with optional attachments.
• Hole diameter = 8.5 mm
• Applicable power: that of the optional Balun used

NOTE:
THE BALUN IS OPTIONAL AND STRONGLY RECOMMENDED (SEE ACCESSORIES AT THE BOTTOM OF THE PAGE).
Although the dipole can be fed directly or with a choke made with coaxial cable, the use of a balun, depending on the type used, helps to better symmetrize the voltages or currents thus allowing for a cleaner radiation pattern.

Material used:

• ERGAL plate
• AL6060T6 tubes
