Great product! No more RFI using my EndFed Antenna. Placed at the output of my Acom 1200S amplifier. My intention is to buy a second one. Thanks Ron!

Unbeatable!
Since I installed two of these insulators in my transmission line I never more had comom mode current or RFI at the station located in the restricted space of an apartment tower Building.
(Please, see my QRZ.com page to confirm).
I give it 10 stars * * * * * * * * * *

I have been using the HyEndFed 5 band antenna for a year. After some research, I decided to experiment with a line isolator. Installed it 0.05 λ below the feed point. It has reduced my noise floor by around 2 s points across the bands especially the lower frequencies. Has not affected the SWR to any significant degree, if anything a slight improvement. I can now work stations previously under the QRM. High-quality construction and delivered to Australia in just under 2 weeks.
