1. Topband: RF attenuators (score: 1): Author: "WD8PKF" <wd8pkf@awcmail.com>; Date: Sat, 20 Aug 2011 14:56:33 -0500; Hello Topbanders I am using an ICE RF attenuator to protect my dedicated receiver inputs. I now need another attenuator for another radio. Since ICE is no longer taking orders or selling their produc; /archives//html/Topband/2011-08/msg00047.html (6,314 bytes)
2. Re: Topband: RF attenuators (score: 1): Author: "Hardy Landskov" <n7rt@cox.net>; Date: Mon, 22 Aug 2011 08:29:36 -0700; Mini-Circuits makes passive attenuators at reasonable prices. They come with BNC, N, and SMA connectors, those being the most popular. They make various power levels also. They do not make attenuator; /archives//html/Topband/2011-08/msg00051.html (7,638 bytes)

Re: Topband: RF attenuators (score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Mon, 22 Aug 2011 17:38:10 -0700; Attenuators for 160M can be built from two carbon resistors for pennies. It's nothing more than a simple voltage divider. 73, Jim K9YC _______________________________________________ UR RST IS ... ..; /archives//html/Topband/2011-08/msg00053.html (7,551 bytes)

Re: Topband: RF attenuators (score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Tue, 23 Aug 2011 09:40:21 -0700; Mini-Circuits is a good company, and I've specified their 4-way VHF/UHF splitters for 35 years for use with the pro wireless mic systems I design for performance and broadcast facilities. BUT -- most; /archives//html/Topband/2011-08/msg00055.html (8,555 bytes)
5. Re: Topband: RF attenuators (score: 1): Author: "Tod" <tod@k0to.us>; Date: Tue, 23 Aug 2011 12:01:56 -0600; Jim is correct. You can look in the ARRL Handbook for resistor combination that will give you the attenuation you desire while keeping the impedance at a suitable value. 73, Tod, K0TO with various At; /archives//html/Topband/2011-08/msg00057.html (7,998 bytes)
6. Re: Topband: RF attenuators (score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Wed, 24 Aug 2011 07:05:14 -0700; I have some measurement capability, but with many other things on my plate, hesitate to repeat work that a very capable guy like Jack has already done. Although I haven't seen his data, I would certa; /archives//html/Topband/2011-08/msg00059.html (9,367 bytes)
7. Re: Topband: RF attenuators (score: 1): Author: "Bill Wichers" <billw@waveform.net>; Date: Wed, 24 Aug 2011 10:46:34 -0400; It would be easy to check if an attenuator is resistive or capacitive by checking if it will pass any DC. If the attenuator is all resistive you should be able to measure a low (relatively, i.e. not; /archives//html/Topband/2011-08/msg00060.html (9,000 bytes)

Re: Topband: RF attenuators (score: 1): Author: Julius Fazekas <phriendly1@yahoo.com>; Date: Wed, 24 Aug 2011 07:45:09 -0700 (PDT); Haven't closely followed this thread, but here's a pretty easy to reproduce splitter, can't imagine the parts costing more than $10, if you're a decent scrounger even less: http://wiki.contesting.com; /archives//html/Topband/2011-08/msg00061.html (10,570 bytes)
9. Re: Topband: RF attenuators (score: 1): Author: "ZR" <zr@jeremy.mv.com>; Date: Wed, 24 Aug 2011 15:04:09 -0400; Ive tested dozens of CATV splitters over 25 or so years and they range from falling apart as high as 7-8MHZ and many good to 80 but useless at 160. By good I mean at least a 10dB RL (2:1 VSWR) and 20; /archives//html/Topband/2011-08/msg00064.html (10,120 bytes)

Re: Topband: RF attenuators (score: 1): Author: Missouri Guy <n0tt1@juno.com>; Date: Thu, 25 Aug 2011 01:57:17 +0000; FWIW...there's also a rather old, but very useful book posted on the net that has tables and formulas for resistive attenutators and a lot of other things. The file is ~3.59 m/b in size. http://136.1; /archives//html/Topband/2011-08/msg00065.html (8,362 bytes)

Re: Topband: RF attenuators (score: 1): Author: Pete Smith <n4zr@contesting.com>; Date: Thu, 25 Aug 2011 10:18:52 -0400; I highly recommend the articles by Jack Smith, K8ZOA on the Clifton Labs web-site. One title talks about 6 dB splitters, but there is much more test data there, including tests of a TV splitter. See; /archives//html/Topband/2011-08/msg00068.html (11,834 bytes)
