Original antennas made in the US, by us, for the greater World

Low Noise Antenna Amplifier/s (LNA) is/are used to enhance the sensitivity of radio receivers, modems or TV sets. They do so by lowering the overall Noise Figure of the receiving system. LNAs are also used to overcome the loss of a long cable. To accomplish this, the Low Noise Amplifier is connected directly to the antenna, before the long cable. When used for this purpose, the LNA is often called an Antenna Amplifier, as its primary objective is to overcome downstream transmission line losses.

All of our antenna amplifiers accept their power from the same coaxial cable delivering the signals. Alternatively, power may be applied directly to the amplifier. Some of our LNAs are intelligent and/or include an internal switch, so they can support bidirectional signal flow (Transmit & Receive).

All Low Noise Antenna Amplifier products in this catalog are designed and manufactured at our facility. We can customize or provide LNAs with specific requirements outside the offerings shown below. Call us at 954-345-5000 for your custom applications and requirements.

Weather Satellite Low Noise Amplifier and Filter
Price: $132.20
Availability: approx. 2 weeks
Item #: LNAU-0122-648 -

    VHF Aviation Band Preamplifier and Filter description Airband Preamplifier and Filter, model LNAU-0122-648, is a 118-136 MHz LNA and Filter combined into a single device. It was designed with Software Defined Receivers (SDRs) in mind, which are notorious for performing poorly where there is a high density of signals in close proximity. This is particularly true of low-cost USB SDR dongles, which cover a wide spectrum of frequencies with a few components. The LNAU-0122-648 provides the signal...

        UHF Amateur Radio Satellite Low Noise Amplifier and Filter
        Price: $143.20
        Availability: Approx 7 days
        Item #: LNAU-0436-648 -

          UHF Amateur Radio Satellite Amplifier and Filter description UHF Amateur Radio Satellite Amplifier and Filter, model LNAU-0436-648, is a 436 MHz LNA and Filter combined into a single device. It provides the signal conditioning needed to improve UHF Ham Satellite downlink signals: it does so by filtering the signals twice, by adding 16 dB of gain (40 times magnification), and providing a low Noise Figure of 1.5 dB to the receiving system. The output filter is very sharp, completely removing...
