The
SIGMA LW40 is an End Fed Longwire antenna. Due to the widely varying impedance at the feed point, an external manual- or autotuner with a wide matching range is required.
An ideal plug and play antenna for camping or on holiday. Can also be used as sloper antenna.
This end-fed wire antenna has on one side a housing with 9:1 UNUN transformer and on the other side an insulator.
The antenna comes completely assembled and is ready to go!
