* = average gain over dipol in free-space / for comparison: 2 el monobander 4 dBd, 3 el 5-6 dBd
** = average gain at 20m above ground (= dBd + 2.15 dB isotropic + about 5 dB ground reflection)
*** the wind loading values include a correction factor, which considers that most of the tubing is round and that never all tubes will be streamed at the same time
**** = outside EU minus 19% tax - subject to change
