End Fed Antenna EFHW-4010-1K-Plus / Installation-plate /LOW SWR/ 63 feet long

Description

This antenna has installation plate with two U-bolts and V-block for installation at towers and poles up to 1.75-inch in diameter.
EFHW-4010-1K-Plus™ Multi-Band End Fed Half Wave Antenna
This is an End-Fed Half-Wave (EFHW*) antenna for 40/20/15 and 10m bands. Unlike many END FED antennas on the market, this one does not require the Antenna Tuner to operate. It is a resonant Half wave on 40m (7MHz) therefore also resonant on second, third, and fourth harmonics. The antenna transformer is optimized for the lowest insertion loss 3.5-30MHz featuring three stacked cores and a transformation ratio of ~56:1 (~2800:50 Ohms) The average loss of less than 0.4dB is unmatched by any other similar transformer on the market proving our worldwide leadership in the design of high ratio-wide bandwidth RF transformers for 3-30MHz.  See the
Insertion loss chart
