EFT40 - End Fed Trap Antenna for 40/30/20m
The EFT40 antenna is an easy to handle end-fed antenna for QRP usage. This resonant antenna covers 3 bands (40m, 30m and
20m) without the need for a tuner. Many small QRP Transceiver don't have an antenna tuner build in.

Being mostly insensitive for environmental influences is the big advantage of such a resonant end-fed antenna. The length of
16,9m brings an easy-handling even at small places. Radials are not necessary. With careful tuning the maximum efficency and
absolute minimum feedline radiation is achievable. With proper mounting no antenna tuner is required or should be used.
However, if necessary an antenna tuner can match this antenna if it is not well-adjusted or mounted in less than perfect
environments.
