Topband: low angle reception using active antennas (score: 1): Author: "Lee K7TJR" <k7tjr@msn.com>; Date: Wed, 5 Dec 2007 19:23:16 -0800; Yes there is a difference in putting an amplifier in the middle of a shortened Hi-Z element rather than at the end using high impedance buffers. The radiation pattern remains virtually the same. You; /archives//html/Topband/2007-12/msg00064.html (9,738 bytes)

Re: Topband: low angle reception using active antennas (score: 1): Author: "Andy Ikin" <andy.ikin@btopenworld.com>; Date: Sat, 8 Dec 2007 12:51:14 -0000; Many thanks for the replies; Lee K7TJR has made a convincing aurgument for using an active mono-pole. I am very close to resolving the IOP3 amplifier degregation by using 4 x 1N4448 diodes connected; /archives//html/Topband/2007-12/msg00084.html (7,932 bytes)
