$4.99 Shipping Condition: New Location: China F/VHF/UHF Impedance SWR Antenna Analyzer For Ham Radio Hobbists INTRODUCTION: AW07A antenna analyzer is a compact battery powered RF impedance analyzer. ... moreIt can test the SWR status of your antenna. Measure the impedance and reactance component and help you to solve antenna problems. This unit combines six basic parts: a variable oscillator. Frequency counter, independent oscillator, 50 ohm RF bridge detector. An A-D converter, and microcontroller. This compact product was built to feed the need for the solid construction and field test. The operating frequency range of this unit goes from HF. And extends up to 490MHz. It is specially designed for analyzing 50ohm antenna system. It measures RF impedances from a few ohms to several hundred ohms. The AW07A is also an L/C meter. Measuring the values of capacitors and inductors. Additionally. It could be a non-precision signal source and frequency counter. With a built-in RF strength meter. It tests the RF field strength near your antenna system, and it’s very useful when you need to know the RF interference status around your station. The AW07A also functions as a non-precision signal source and frequency counter. The operating frequency range of this unit extends from 1.5 to 71 MHz in six overlapping bands. And includes SWR measurements on 85-185MHz, 300-490 MHz. FEATURES LIST: 1. SINGNAL SOURCE 2. CAPACITANCE METER 3. INDUCTANCE METER 4. SHOW REACTANCE VALUE 5. SHOW IMPEDANCE VALUE 6.

General Radio 1606-B Radio Frequency Bridge for Testing HAM Radio Antennas etc
This bridge came from a business here in town that closed down and was used in a working environment. Unit deals with frequencies between 400 khz- 60 mhz. Direct Reading in ohms. Adaptable to coaxial connectors. Seems to be very similar to the"A" model whose user guide is readily available online. A bridge like this is intended to be used between a signal generator and null detector assembly for the accurate measurement of the resistance and reactance of antennas. Transmission lines, networks and components. Unit is untested by me. Auction is intended for someone with the knowledge to address any operational or performance issues with the unit should there be any. Being sold as is. Cosmetically has wear and some scratches with a stencil on 1 side. Obviously very high quality construction. Weight is 22 pounds Shipping is UPS Insured ... morein USA only. Good Luck!

Vintage Heathkit IT-2240 Digital LC Bench Capacitor Meter Ham Radio Receiver Cap
Vintage Heathkit IT-2240 LC Meter From my personal collection. I acquired it from the original owner(a Ham operator that passed) He and I are not smokers. This instrument is hard to find in good condition. I used it for radio repair years back. But now it just sits on the shelf. Comes with original manual and calibration caps. Manuals binding is shot. However all is there including the foldouts/schematic. I would assume that a calibration check would be in order. I have never messed with it. Great to repair vintage receivers transmitters or add to your collection. Vintage electronics, sold AS IS. I will pack well to prevent damage. Shipping USA Only. UPS. Well packed, $24.00, If less, I will refund

Heathkit IT-28 Capacitor Checker Resistance Bridge,6E5 Green Eye Tube,Ham Radio
This auction is for a vintage Heathkit Model IT-28 Capacitor checker/Resistance bridge. It contains the following tubes: 6AX4. 6BN8. And a 6E5 green eye indicator tube. I took the cover off and removed and tested the tubes. All tubes tested great! The 6BN8 had strong readings on all three sections and the 6AX4 had a strong reading. The 6E5 tube was bright green in both the open and closed positions on the tester. No further testing has been done with this instrument. So I am uncertain about it's calibration or general working condition. All the switches and knobs seem to work fine and it is in nice overall condition with just a little wear and staining. This item is being sold as pictured and"as-is" Take a look at all of the pictures for your best cosmetic description!
