Re: [time-nuts] Lucent 40 dB Antenna
I bought mine because of the gain, but on +5V it performs worse than a 38 dBi antenna, quite a lot worse. I'm wonder whether it needs more volts, or whether it's simply broken. It was ex-equipment, and not in very good shape, but it was described as used so I'll just write off the loss, I suppose. Update, I mentioned the problem to the seller, and got an immediate fill refund. Nice to have no arguments!

Re: [time-nuts] Lucent 40 dB Antenna
Hi Joe, 40dB is not needed when you have a short (10m) /good antenna cable. Then 26dB will be plenty fine. Howver going to 20 or 30+ meters using standard RG58 will be a problem with 26dB. Ofcause what matters is the attenuation at L1 with your cable. Better cable can be longer... You do not need an spectrum/network analyzer. Take a your antenna and receiver to a good site, if you installation site might be marginal. Your C/N0 (snr) should be around or above 50dBHz for high elevation satellites. Then compare the C/N0 values for you antenna at your workshop, to see how much worse than perfect that site is. If using a Tbolt remember to change from Trimble AMU into dBHz. Note that LNA dB amplification not generally translate direcly into dB carrier to noise ratio. -- Björn PS I got a small batch of HP timing antennas new in box for around $25 a piece some years ago... :-) DS Mine arrived in the same manner. It works but I can't tell any real difference between it and my 26 dB antenna, switching between them when mounted on the corner of the roof of my workshop.

Re: [time-nuts] Lucent 40 dB Antenna
Bjorn, My setup is a Lucent 26 dB antenna on a bracket on the edge of the roof at the corner of my workshop feeding about 20 feet of 9913 coax (7.5 dB attenuation per 100 feet @ 2.4 GHz) to a 58536A four way splitter that feeds a Z3816A, Z3805A, TBolt, with a 'spare' for playing with. The splitter uses about 2 feet of 9913 to the Z3816A and the Z3805A and the TBolt is fed with about 6 feet of RG58 with BNC connectors and adapters for BNC to F and BNC to N. With SatStat and a Z3816A, C/N is typically 30 to 50. With TBoltMon or Lady Heather and a TBolt, dBc also typically 30 to 50. I didn't see much difference on either with switching antennas but I suspect I have a fair amount of signal to start with (Lat of 30 degrees but under trees).

Re: [time-nuts] Lucent 40 dB Antenna
I think I got lucky. Despite the almost nonexistent packing, my antenna looks like reasonable wear and tear for a used item and didn't suffer much from shipping, and it passed an operational check on the bench today. Setup was an 8566B SA as receiver, bias tee on the input, 5vdc to the antenna, and about 10 inches of RG8 to the Lucent antenna, which was hand held. The source was a GS-100 GPS simulator into a log periodic that was only designed for 400 - 1000MHz but it was what I had in reach. Distance between the source antenna and the DUT was about 12. A far from optimal, cobbled together setup but it was quick and easy. With the GS-100 output connected to the SA through 18 of RG8, the signal level was set to -70 dbm for a reference. When the aforementioned crude lash up was put in place with the antenna powered up, the signal level on the SA increased 10-12 db. This was far from scientific but it gives me enough confidence that at next opportunity I can take it up into the attic for further testing.

Re: [time-nuts] Lucent 40 dB Antenna
Steve will be interesting to hear how it goes. Thats a reasonable price it seems and the antenna looks like it could handle abuse pretty well.

Re: [time-nuts] Lucent 40 dB Antenna
You just need a spectrum analyzer. The signal source would be the birds. I forget who claimed the GPS signals are beneath the thermal noise. I'm quite sure I could see them on my spectrum analyzer and will check this weekend. These work fine if all you need is L-band: http://www.ebay.com/itm/AVCOM-PSA-45D-PORTABLE-SPECTRUM-ANALYZER-L-BAND-/110838378615?pt=BI_Analyzershash=item19ce7b7077 You will find two vendors on Ebay. I think I mentioned the story before. Just get the cheap one and check it out immediately. They have a few hundred, so you can get a swap if it doesn't work. Expect to spend $50 to rebuild the Lion pack. Even then, the unit drains the pack in a few days if you don't use it right away. None of the units have ethernet unfortunately. I paid $40 more for my unit than the price listed in the ad, and was supposed to get ethernet, but it never materialized. I'm going to bug the guy to send me a junker unit since I paid extra and didn't get what was advertised. The current advert doesn't mention ethernet. I manged to get a serial port card from the vendor. It has the ethernet traces on the PCB, but not populated. Don't expect a lot of frequency accuracy. This is not HP. It is technician gear. The units are pulls from mil gear and were rack mounted at one point. No feet, bail, or case included. Avcom still exists, but their accessories are quite expensive.

Re: [time-nuts] Lucent 40 dB Antenna
Paul, I believe I read in an earlier post that someone was using one of these with a Tbolt, which is 5 volts to the antenna. Hope I'm not mistaken! I didn't hear any rattles when I shook the unit so I'm keeping my fingers crossed. They do appear to be pretty rugged so I'm hoping for the best. The reply from the seller ignored my poor packing complaint and said this is used, it can not all are the same. our guaranteed is you can ask for refund if it can not works. I assume they have a boatload of them bought very cheaply and they are playing the odds that they will make more from replacing a few that don't survive shipping than they would if they spent a bit more on packing material for all shipments. We live in a National Historic District so no outdoor antennas here. My antennas are in the attic above the third floor, putting them about 40 ft AGL. So far the shingled roof hasn't been a major obstacle and the GPS antennas are above the HVAC ductwork.

You might have to paint the dish. I believe Gary is referring to the FCC's OTARD (Over-the-Air Reception Devices) Rule, 47 C.F.R. Section 1.4000, which (with some exceptions) preempts local restrictions that impair the installation, maintenance, or use of antennas used to receive video programming or certain point-to-point wireless signals (e.g., wireless last mile Internet service). However, it does not preempt local restrictions on antennas used for GPS, AM or FM broadcast reception, SWL, satellite radio, etc., etc. For a quick guide to the OTARD Rule, see http://www.fcc.gov/guides/over-air-reception-devices-rule.

For the dishes and HD antennas, I just found the FCC rules and gave them to the person that wanted to put up the antennas. Basically you cite chapter and verse and the HOA caves.

Is everyone buying these because they have 40dB gain or because they are the only reasonably priced GPS timing antennas on eBay right now?

What might be the cause of the muiltipath that the choke ring is helping with I've been working with RF long enough not to expect easy answers when it comes to multipath. It's pretty much always there, sometimes in sufficient quantity to be really troublesome, other times (as with GPS at my location) enough to notice but not to be really troublesome. Typical suburban neighborhood, 2-story brick houses on ~80-foot lots. The antennas have been tried (i) on the second floor (under a plaster ceiling + asphalt shingle roof); (ii) in the attic (under the roof only); and (iii) on a mast about 15' above the roof peak (~45' AGL). The c/n improves ~ 7 dB going from (i) to (ii) and another ~2 dB going from (ii) to (iii) for all antennas, while the relative advantage in positioning and deviation of the choke ring is essentially unchanged. After experimenting, I installed the choke ring antenna in the attic peak. A ground plane placed under the mag mount and the Bullet 3 did not improve the positioning or deviation.

Unless there is a real reason to open it don't. Weather seals can be a devil to get sealed again. If it isn't seal moisture seeps in overtime and destroys the unit. Regards Paul.

Re: [time-nuts] Lucent 40 dB Antenna
The one I got there was a pretty good size hit where the two sections go together. Otherwise I would not have. Before putting it together I did what I use to do with optics. 24 hours in a desicant jar then filled with dry nitrogen. All thanks to a friend who has access to such.

Chuck wrote: My Lucent antenna arrived today. Has anyone compared this antenna with the mushroom that came from China with the used Thunderbolts??? I have five GPS antennas -- a Garmin mag-mount puck designed for vehicular use, a Garmin marine mushroom, a Lucent timing antenna like yours, a Trimble Bullet 3 (the antenna specified by Trimble for use with the Tbolt), and an Aerotenna choke-ring survey antenna. Deployed in the same location, they all give very similar signal reports from the Tbolt and track the same number of satellites (remember, the Tbolt reports the carrier/noise ratio, not raw signal strength, and c/n is closely correlated with the signal environment at the antenna location unless an antenna has way too little gain or a very noisy preamp). This suggests that they all have sufficient gain and low enough noise to work properly with a Tbolt. The one difference I observe is that the choke-ring antenna shows consistently less variability in its surveyed position, and lower deviation of both the 10 MHz and pps, than all of the others. I assume that this is due to reduced multipath, but I have no way to verify it.
