I do agree, but to be fully pedantic,

  L1 and L2 are hand-wound microwave chokes with
  very high self-resonant frequency, mounted
  perpendicular to one another and clear of the
  ground plane. Wind 14 turns, air-cored, 1mm
  inside diameter from 7cm lengths of 32swg
  enamelled copper wire. Checked with the tracking
  generator on a Marconi 2383 SA, these were good
  to 4 GHz.
