I've never used one, but based on its length it's probably going to be very inefficient anywhere below about 40M.  And a trapped vertical with a proper ground system will probably outperform it on any band.  Nine bands and only 18' tall with no ground system (and only $200)?  It sounds too good to be true, and therefor it is.  Sorry to burst your bubble.

Hello, The facts are that this antenna is 18ft length. The antenna will work best in the range of frequencies where the length is between a 1/4 wave and 5/8 wave And tuned.
Otherwise it is a reasonably constructed antenna.

Hi,
I purchased one of these antennas when they were sold under the SNOWDONIA brand. I persisted with it for almost 3 months but it was just a length of noise!!! Most disappointing antenna I've had the misfortune to buy. Using a Delta loop for 80, 40 17 15 now and a Sirio GainMaster vertical for 15 12 11 and 10. I have a tiny Irish garden and have to seriously comprimise but I can still work the Americas, Europe, Middle East and Indonesia and North Africa. Not bad in my opinion. HF360 may make a great flagpole but not an antenna.
