The Z-Match Tuner - qsl.net
Nov 1, 2006 · But the Z-match tuner is NOT a truly balanced tuner. It’s best described as a “semi-balanced” tuner. It simulates an L network and remains balanced over a relatively large impedance range.
A Homebrew Z-Match Transmatch - WB3GCK QRP Amateur Radio
Apr 18, 2020 · A well-designed Z-match tuner has a high Q and is more efficient (less lossy) than other types of tuners. The fixed inductor simplifies construction (no taps or rollers needed). Using a toroid inductor and some small poly-film variable capacitors, the Z-match can be built into a very compact package.
FRI-Match ATU, a single-coil Z-Match type: - XS4ALL Klantenservice
This ATU, I call my design FRI-Match, has been devised in 1972 as an unbalanced tuner for improving the SWR at the transmitter end of coaxial feeders to resonant antennas (eg verticals, dipoles, trapped dipoles, G5RVs, Yagis, loopquads etc.).

The Z Match is a parallel tuned circuit with link coupling to the antenna. The two varia-ble capacitors with the tapped tuning coil offers a wide tuning range. It should be possi-ble to use the tuner on all HF bands from 80 metres to 10 metres to match balanced or single ended antennas.
Based on all the experimental work I have carried out, here is what I select as a simple design which has been fine tuned to match a wide range of antenna impedance conditions: The circuit diagram is shown in figure 1.
Multi Z Tuner 40m-10m - QRPGuys
The QRPGuys Multi-Tuner is a Z-match design that will match a wide range of coax fed, long wire, and balanced line antennas, like high-impedance, low-loss UHF twinlead or ladder line for 40m-10m. The Multi-Z tuner is based on a design by Charlie Lofgren, W6JJZ.
Homebrew Antenna Tuner - A Best of Breed Version - Ham …
The Z-Match Network While browsing around for QRP tuners, the Z-Match caught my attention. The Z-match network was originally described by R. W. Johnson, W6MUR in the July 1954 edition of the QST magazine published by the ARRL.
ZM-4 Z-match antenna tuner kit review - marxy
Sep 2, 2021 · Z-Matches are a versatile antenna tuner although I understand they can be lossy. This kit is well done but the switch wiring and panel metalwork takes some effort. When boxed up it's a compact and strong little tuner that will work well for portable QRP operation.
The Z-Match is built around the multiband tank circuit that came into use around 1950 to reduce bandswitching chores in the tube rigs of the period. This circuit simultaneously tunes through two frequency ranges--for example, 3.5 to 10.5 Mhz and 10 to 30 MHz--to cover the full HF spectrum.
A Homebrew Z-Match Tuner - qsl.net
Matches balanced loads without the use of lossy baluns. Being a parallel resonant circuit, the Z-match can provide some band-pass filtering for your receiver and harmonic attenuation for your transmitter. A well-designed Z-match tuner has a high Q and is more efficient (less lossy) than other types of tuners.
QRP Z-Match Manual Antenna Tuner 3-28 MHz for HAM Radio
Aug 28, 2023 · Z-match manual tune: Power: rated power 5W, intermittent power 10W; Net weight: 250g; Size: 88* 83*38mm, excluding protruding parts; Connector: BNC; Matching impedance range: 25 to 2500 ohms; Frequency: 3-28 MHz.
Emtech ZM-2 Antenna Tuner Kit - N5ESE
The Emtech ZM-2 Antenna Tuner is a nifty little portable transmatch for QRP (low power). It utilizes the well-known Z-match circuit, which is especially useful for balanced antennas (like dipoles and loops).
simple z match hf tuner The Z Match is really a basic L Match consisting of a series capcitor C2a+C2b and variable shunt inductor L1 that is coupled to the antenna using the RF transformer action of L1/L2.
ZMatch Antenna Tuners - W5USJ
Compact Z-Match: Intended only for coax fed antennas, this one is built in a gray-painted Bud Mini Box. The tuning controls on the top are the same as the deluxe matcher above. The switch on the end above the antenna BNC selects the hi and low Z coupling links.
Z-MATCH - VK6YSF
The Z-Match antenna matching unit while not exclusively designed for a balanced antenna system is particularly well suited to this configuration.
Reviews For: ZM-4 QRP ATU Kit by QRPProject.de - eHam.net
The ZM-4 is a QRP Z-Match ATU Kit. Housed in a rugged extruded aluminium case with a large torroid and PCB. No additional parts to buy - the kit includes everything bar the tools and time. Balanced and Unbalanced output from Banana Jacks and BNC. Matches high and low Z antennas from 160m to 10m. Built in Wheatstone Bridge for SWR sensing.
QRP TO 50 WATT Z-MATCH TUNER - The Trek BBS
The Z-match tuner is designed to handle balanced loads such as a doublet fed with balanced feedline or a loop. Since it is a balanced tuner, it does not need the balun that so many commercial tuners require to feed balanced feedline.
G3VGR's Single Coil Z-Match Tuner - qsl.net
My favourite antenna tuner is the single coil Z-Match. I tend to use ladder-line feeder instead of coax, so I believe a tuner designed for balanced feeder is a much better solution than a T-Match or SPC using an external 4:1 balun or similar.
Reviews For: Wanzer Z-Match - eHam.net
A "Z-Match" that is mechanically & electrically sound is a very good buy at a hamfest/swapmeet or second hand. The components were good quality, & the unit itself was robust. I can't state exactly what range of impedances it would match, but it is impressive.
