This just in from a satisfied Loftenna user...
"Many thanks for getting the “Loftenna” out to me before Xmas given me something to play with!
I installed it today (in the loft) and what can I say it works…..! I previously only had a 20m wire dipole in my loft but with your Loftenna into an MFJ-969 ATU using 10w on an FT-840 5mins after coming down the ladder I got 5-7 report from Romania on 15m – so many more bands now opening new doors to me.
I’ve checked the SWR on all bands 80-10 found it below 2 on most when bypassing the ATU and get easily get perfect SWR with the ATU."
