3x Sloper 40m


Each sloper is feeded by 20m of Ecoflex-10 directly solded on the antenna part and with PL Teflon plug (male) at the end.

Instructions “How To” included with the antenna.

The same system installed and tested @ HamTenna farm provided following results :

Gain : 9.3dBi
F/B : 15.9db
SWR : <1.4 if feeded directly by 50 Ohm coax
Elevation Angle : 6deg on real ground (with lowest part @ 7.5m agl)



Set of 3 Slopers for the 40m band to be installed along the (non-metallic) tower’ rods.
The system is tested for an angle of the tie rods around 30°/35° with the lowest point at least 2.5m a.g.l..
Each sloper, made in awg18 wire, can slide along the tie rod (through stainless steel connectors) so that it can be lowered in case of calibration or maintenance without the need to unplug the tie rod.
The kit includes the insulator from the top of the tower, 10m of rope sufficient to anchor it to the base of the bracing and 20m coaxial cable eachone (ecoflex-10 already UHF plugged) already connected to the various slopers for connection to a switching system (coaxial switch) not included.
Note: This version does not include short circuit relays for unused slopers.

Insulators: high voltage ceramic
Ropes: kevlar
Coaxial cable: Ecoflex-10
Connectors: UHF (PL)

Loading Power : >3kW@ SWR<2:1

SWR @ correct installation : <1.5:1 on entire band
