Hi, SMC connectors is available over the desk in my hometown - which is a fairly remote part of our large globe. Price is the same range as SMA-connectors. 5 sec on Xbay finds 4 connectors and shipping for $15. How do you connect a single Bias-T to give DC both to splitter and antenna? -- Björn Hi Claude, since the SMC jack is also DC-connected to the antenna output (through an inductor) to power the antenna, the unit also works well if you feed 4V to 5V into the unit through the antenna port! That can be done using an L-band-capable standard Bias-T, and then leaving the SMC connector open. You may find a Bias-t more easily than an SMC cable. BTW: if you do it that way, the upper limit on the voltage is limited by the internal Linear Technology voltage regulator, so you can go way above 5V without a problem. The unit shouldn't consume more than 25mA or so that way... Bye, Said In a message dated 1/27/2010 16:51:28 Pacific Standard Time, va2...@aei.ca writes: Hello !

I was going to offer you a 50 cm cable with a SMC male connector on one end for free when I found this supplier http://www.surplussales.com/Connectors/SMC.html who sends wordlwide without minimum order. Sure it will cost you less than the shipping from Spain, and my cable is 30+ years old. Regards Ignacio, EB4APL Claude Houde wrote: Hello !

Re: [time-nuts] HP 58516A GPS distribution amplifier information
Hi I found a SMC-BNC adapter of the correct orientation in the bottom of my junk box. Somehow I doubt I'll ever use it for anything else. BNC cables and jacks are something I can find easily. The top of the unit is held on with screws so getting inside it should not be very hard. You could swap the SMC out to something that's more common for power distribution. Maybe an APC-7 ... My guess is they used the SMC because it's unusual. That way you don't get a cable with 30 VDC on it hooked where it shouldn't go. If you did run a 30 volt supply the dc could do some damage. Of course 30 volts on that unit connected to a normal antenna would do some damage as well.

Re: [time-nuts] HP 58516A GPS distribution amplifier information
Hi I'm sitting here looking at the spec sheet for the splitter: A normal four way splitter should have a loss of a bit over 6 db. The reason that's bad is that it may degrade the noise figure at your otherwise perfect receiver (and sub 1 db noise figure antenna) by 6 db. (it may also do absolutely nothing bad at all) The splitter has a rated noise figure of 7 db max / 5 db typical. It has a gain that may be a loss of 3 db or a gain of 3 db. Worst case, it's got a -3db gain and a 7 db noise figure. It may degrade the noise figure at the receiver by 10 db. Best case it's got 3 db of gain and a 5 db noise figure. That's still a noise figure hit of 5 db. All of that is pretty easy to blow holes in as far as a real / normally operating system is concerned. I *think* it's pretty close in the limit case though. If it is close, then the part (yes I bought one to) might improve things by 1 db. It also might degrade things by 4 db under the worst case conditions where it likely matters. Am I missing something here? Obviously it does more than split. It may have better isolation than a conventional splitter. It also has the cute little DC loads in it. Seems like a little bit more RF gain might have been a good idea.

Re: [time-nuts] HP 58516A GPS distribution amplifier information
Hi I think the big issue with two receivers is if one of them powers down and the other stays up. Then you try to back feed the one that's power down. That may or may not be good for it's health. I'd hope there's a diode or something like a diode in the DC path to protect it. It would be pretty easy to double check.

Re: [time-nuts] HP 58516A GPS distribution amplifier information
Hi Bob, If you get a smart splitter they might have a network option or even as standard take DC for the antenna from any port on the splitter. This is from http://www.symmetricom.com/link.cfm?lid=4907 The purpose of the micro-controller is to sense the bias voltage present on each of the output ports, and it always selects the lowest numbered port (1, 2, 3 or 4) to supply power to the splitter and to the GPS antenna. Each of the three remaining ports is configured by the micro-controller to sink a standby current of 25mA @5V. -- Björn Hi I think the big issue with two receivers is if one of them powers down and the other stays up.

Hi Claude, since the SMC jack is also DC-connected to the antenna output (through an inductor) to power the antenna, the unit also works well if you feed 4V to 5V into the unit through the antenna port! That can be done using an L-band-capable standard Bias-T, and then leaving the SMC connector open. You may find a Bias-t more easily than an SMC cable. BTW: if you do it that way, the upper limit on the voltage is limited by the internal Linear Technology voltage regulator, so you can go way above 5V without a problem. The unit shouldn't consume more than 25mA or so that way... Bye, Said In a message dated 1/27/2010 16:51:28 Pacific Standard Time, va2...@aei.ca writes: Hello !
