1090 Mhz Amplifier


Just built a new antenna that should give 15dbi. I have used a low cost 18 dB amplifier for Satellite L-band - Mhz , about 4 years ago when I started this hobby. Please see following thread for details. The amp I obtained is 38dB Gain and 0. Mine is going to detect very weak signals at the antenna , a high gain antenna, and then boost up a hell of a lot to send it down the coax.

IF its got enough signal strength, the GPS gets displayed. A poor antenna will show less gps positions and more non adsb transponder signals. When I listen to digital signals, it never ceases to amaze me how the machine can detect the data when a human cannot even detect that a signal exists. My latest antenna is a 8 stage J-pole co-linear. Next version will be more elements and made of solid copper pipe that enables more accurate measurements.

So far, without an amp, and using a old oil can, its getting occasionally over nm in 3 areas of the compass. May be these two meet your requirements. I have not used these. If someone has used it, please post your opinion about it. Depends of your location. If most of your planes are seen at a big distance, then yes a preamp would help. If you have lots of planes close-by, the preamp might overload the input in your receiver and actually make it loose samples.

I have tried a simple wideband preamp and, in my place, it just made things worse. Even without the preamp I have adjusted the receiver gain at 38dB to maximize the samples. Now I have bought a preamp with two ceramic filters MHz and it seems to have improved my rates - but only if I power it at 5V and set my own receiver gain as low as 4dB!

Are you sure these are Ceramic Filters? Most likely these are low cost SAW filters. In photo at Ebay, these resemble SAW filters. If you see the chips closely and read their markings, you may find if these are SAW or Ceramic. In front of this I also have installed the FA filter. This is NOT a low noise amplifier, which is narrow band.

This one is a broad band and suitable only for boosting a signal down a long line, not boost signals. The regular grey sdr-rtl excluding the FA versions dongles can feed Bias-t.

V1 and 2 require a solder connection. Wideband is probably not a good idea for our use, unless you use a cavity or other filter beforehand. It will probably amplify too much noise and overload the receiver.

Has anyone else had a similar experience? Mine works fine. Check that the antenna in at RF in. On mine I have a FA filter in front, but it was working even without one, just less decoded signals.

Of course this depends of location and what RF pollution you have there. This adds 35dB of gain, you need to reduce it with approx that amount! Please see photo below. It proved to be deaf. The second case was Pro Stick Plus blue. It has a mhz filter, but it is not located between antenna and rf amplifier chip the filter is located between rf amp and tuner. Thanks for the reply however your amp and my amp are not the same, yours is broad band, mine is narrow band and in a way a bit like a filter as it only amplifies the segment.

Tuner AGC on or off. Config on or off. Is there or are there options in Flight Aware to be able to control gain for optimum performance with an amplifier?

Thanks Ramjet. What type of Preamp you want to use? Its a bit like listening for Voyager 1. Here is a cheap Bias Tee, for feeding 5V over the coax. V3 can do it in software. I have a few powering uptronics amps. Redo the gain optimisation after you add an amp. You may need to lower the setting considerably.

Yes, I have twice faced same situation, but not with this one.

Uputronics filtered preamps for improved reception on RF low noise amplifier, with standard female connectors, suitable for connecting most devices. In case we have enough money and want to invest in a good antenna we can buy a ready-made collinear antenna eg. The LNA uses a low noise figure high linearity two stage MGA amplifier chip and three stages of filtering to ensure that strong signals or interference will not overload either the amplifier or SDR dongle. They write that they are selling this antenna at cost in order. Dimensions USB device only 87mm x 27mm 3. It operates over the frequency range of MHz to MHz. You cannot order more than units of a single product per order. The AS can be used with any passive antenna like the GP or a discone antenna. Limited Time Sale Easy Return.

KU LNA 1090-2 A TM, Selective Low Noise Amplifier

This is the type of amplifier that is often supplied with a kit for indoor panel antenna but it can also be purchased alone. The power supply is via USB adapter. I used a battery charger that has a 5V USB output to use it as a power bank. The one i have got is slightly different from the picture above, it has a red LED and no antenna logo printed. The first thing is did was opening it, here is the circuit:. Full screen image link here. Most of the components are resistors, capacitors and inductors.

This post describes the construction details of such a filter. Although a cavity filter could have fitted the job of this narrow band application I had already chosen to build an interdigital filter. The designs found on internet pretty much agreed on the dimensions so i ended up using this online Interdigital Bandpass Filter designer.

Besides the guitar itself, a decent guitar amp is one of the most significant purchase a guitarist will make. Indeed, an amp is arguably more important to your overall tone than the guitar! Your first 'proper' amp is likely to be based on something that your heroes play, but you'll soon end up wanting something that better fits your own playing style. Whether you use overdrive pedals to provide your gain, or you're looking for your amp to provide full bore distortion on its own, the amp you go for will determine the overall character your audience hears out front. There's a dizzying array of amps on the market, so you need to do some thorough research before pulling the trigger to figure out what's right for you. We've listed them in price order to make your life a little easier, and we've even found the best prices for 'em, too!

Not long after my last post on this subject, back in January, the preamp I had mounted in the box at the top of 30ft of pole strapped to the side of my house failed and I was forced to removed that particular ADS-B aircraft tracker. I still had my loft unit running and working very well with my home brew two element J-pole collinear. Tony built this all for me without the filter so I had to make some tweaks inside.
