I posted on this antenna on eham review not long ago.
Right out of the box and up in the air—– no trimming at all.
SWR about 1.5 to 1 on all 3 bands. I’ve had good experience with other LNR
end fed wires . A bit of wire trimming was needed.
But this one needed no adjustment: 25 ft rg174 coax attached to the tuner box
at 8ft height and the far end at 20ft.
I have the EF-MTR and have used it on numerous SOTA activations using a 33.5 ft RG-174 Coax and an Elecraft KX3. The KX3 immediately displays 1.0:1 on 40 & 20 when the tuner is activated. Signal reports are comparable to my dipole IF i get the EF-MTR up high enough. Very easy to deploy with a throw weight and line. Haven’t used it on 30 as I lost the 30 mtr tuning stub. Can someone from LNR contact me concerning a replacement stub. The “Contact US” submission apparently isn’t working and there is no phone number on the website.

I had recently ordered this antenna and decided to use it for Field Day this past weekend. Setup 20′ vertical on my crappie pole then horizontal and up maybe 5 more feet to a tree, running SSE. Took about 15 minutes. Used my MTR-3, no tuner, 3×3.7v LiIon batteries, AME PortaPaddle and ATH ANC-3 earbuds. One the air about 6 hours total Sat/Sun. Results: 48 sections in 36 states with 100 (my goal) total contacts. 1.5:1 SWR on 20/40m.
VERY pleased with both quality of construction and its ability. I ran ‘S&P’ rather than trying to CQ, and I think only a couple stations didn’t hear my 5W.
I am in Oklahoma but was able to work ENY, NFL, LAX, WWA, WY, CT etc as well as BC and SK in western Canade off what should have been the ‘back’.
