4 el. 15/10m Yagi
15/10 meter 4 element beam Yagi (21-28 MHz) DXBeam (Ref. DXD1510-4)
15/10 meter 4 element beam Yagi (21-28 MHz).
No traps or relays, one single coaxial cable.
This design uses a Reflector-Driven element on 15m and a Driven element-Director on 10m.

Greases supplied
2 kinds of grease are supplied with your antenna:
• Aluminum contact grease: Professional grease containing 30% aluminum particles, recommended for the assembly of aluminum antenna tubes. Prevents binding, corrosion and the formation of aluminum oxide, and allows easy dismantling of antennas after several years.
• Copper conductive grease: Professional conductive grease with a copper base, recommended for all hardware requiring a sound and lasting electrical contact. Prevents oxydisation, damp ingress, and limits chemical reaction between stainless steel and aluminum.
Balun or no Balun ?
• This antenna does not require any balun.
• To avoid having stray current on the braid of a coaxial cable (often the cause of RF and/or TVI/BCI), you can make your own 1:1 choke balun with coaxial cable. Explanations are provided with antenna assembly instructions. (See also our F.A.Q).
