141. [TowerTalk] Vertical antennas (score: 1): Author: w8ji.tom@MCIONE.com (w8ji.tom); Date: Wed, 28 Oct 1998 12:22:52 -0500; Hi Carlau, speak of a four sqare arrays. First, let me say they both seem to be good verticals. The Unihat is another one, although it seems to have problems handling high power.

If the tuner really absorbs reflected power and dissipates it, shouldn't it get hot? You have that backwards, the BUL; /archives//html/Towertalk/1998-09/msg00210.html (10,129 bytes)
