June 12, 2018It’s been 2 years since I’ve started building HP Triplexer and BPFs and 5 years since my Low Power Triplexer project has been started. No single triplexer failure has been reported yet.

May 12, 2018.  Please, listen to an Audio file  how the most difficult 10 and 20 meter bands could sound (with Triplexer, BPFs and 100W output power) . OR2F and ON5RA  (worked as OT70OSB) during their test of WRTC-2018 equipment. You can find this audio file on this page as well.

April 05, 2018.   Low Power 200W Triplexer  in a Hammond 1411RU (8″ x 6″ x 3.5″) enclosure will be sold by Array Solutions starting  April 2018.

January 20, 2018.   20M Low Power 200W BPF completed in a Hammond 1411MU (6″ x 3″ x 3″) enclosure. It is better than – 0.3dB of Insertion Loss, band attenuation is better than -60dB with VSWR below 1.1.

November 4, 2017.  160M High Power LPF completed in a Hammond 1411ZU (17″ x 5″ x 4″) enclosure. It is better than -0.1dB of Insertion Loss, band attenuation is better than -65dB with VSWR below 1.1.

October 12, 2017.  40, 80 meter BPFs and 160M LPF completed in a Hammond 1444-1773 (17″ x 7″ x 3″) enclosure. Now, all band’s BPFs/LPF can be built in two different enclosure types, optimized for a wall installation or to be used as a “box tower”.

October 1, 2017.  The first 160M High Power LPF completed in a Hammond 1444-1773 (17″ x 7″ x 3″) enclosure. It is better than -65dB of isolation for 80 and 40 meter bands.

May 31, 2017.  The first antenna switch I’ve ever found with 50 Ohm loads on every port is available from RemoteQTH.com. It is a -71dB of isolation on 28MHz and better for other bands.

May 20, 2017.  High Power 3000 watt 40/80 meter Diplexer completed. 

May 12, 2017.  New Triplexer with BPFs  set 1500W (2000W PEP) completed. 

Mar 15, 2017.  Low Power Triplexer in a new 1411RU / 1411UU enclosure completed.

Feb 1, 2017.   I started moving my old website to this one.

Thank you for your interest!
