MFJ-974HB Balanced Line Tuner 10-160M, 300W SSB / 150W CW
This is a factory display unit from the MFJ hamfest booth. It is 100% functional. Cosmetic issues are slight. The paint has a few tiny nicks here and there from handling, and there is some adhesive residue and some rub marks on the top. No missing screws, no extra screw holes. If this was a used tuner, it would be in really good condition. Be sure to read the general notes about factory demo/display units at the bottom.
Made in the USA.
This tuner will handle antenna connections using coax or balanced line (i.e., open line or ladder line).
I tested this on my desk, using the coax connector. I tuned 20 meters at 100 watts, and compared the meter to my Daiwa CN-901HP, and it was a solid match. I did not test an antenna on the balanced line connection, since I don't have a ladder line feed coming in. The lamp works fine. If there is a problem I missed, this does have a 30 day warramty fron FatCat.Parts.
Here is what the MFJ website has to say about this tuner:
The MFJ-974HB gives you excellent current balance, very wide matching range(12-2000 Ohms) and covers 1.8 through 54 MHz continuously including all WARC bands, 160 Meters, 6 Meters and the new 60 Meter band. Handles 300 Watts SSB PEP and 150 Watts CW.
Tuning is fast and easy - - just three tuning controls. You can even adjust for highly efficient broadband low-Q operation or use higher Q when you encounter extreme loads.
A large three-inch lighted Cross-Needle SWR/Wattmeter lets you read SWR, peak or average forward and reflected power all at a glance on 300 or 30 Watt ranges.
A ground post is provided to ground one output terminal so you can also tune random wires and coax fed antennas.
The MFJ-974HB tunes any balanced lines including 600 Ohm open wire line, 450/300 Ohm ladder lines, 300/72 Ohm twin lead - - shielded or unshielded.
Superb current balance minimizes feedline radiation that can cause troublesome TVI and RFI, painful RF bites, mysterious RF feedback problems and radiation pattern distortion.
The MFJ-974HB is a fully balanced wide range T-Network using four gear driven 1000-Volt air variable capacitors and high-Q air wound tapped inductor for 80-10 Meters and separate inductors for 6 and 160 Meters. The tuning components are mounted symmetrically to insure electrical balance.
A 1:1 current balun is placed on the low impedance 50 input side to convert the balanced T-Network to unbalanced operation. The balun is made of 50 ferrite beads on RG-303 Teflon coax to give exceptional and efficient isolation. It stays cool even at maximum power.
Balanced Line = Extremely Low Loss
Balanced lines give extremely low loss.
Doublet, horizontal loop, vertical loop, quad, double extended Zepp, Lazy H, W8JK antennas all give efficient multi-band operation when fed with balanced lines.
GENERAL NOTE ABOUT FACTORY DEMO/DISPLAY UNITS:
NEW (OPEN BOX): This is a new unit, in that it has never been sold or placed into service. This is a fully-functional unit that was used as a static display either in MFJ's offices or as part of MFJ's hamfest display booth. As such, it may have cosmetic scuffs or scrapes on the cabinet, it may have some extra, tiny holes (usually two at the most) in the cabinet from security brackets on the hamfest displays. Hamfest displays often had a "show sticker" applied to the cabinet. If so, those have been removed, and there may be some adhesive residue left where the sticker once was. Goo-Gone and rubbing with a thumbnail will usually remove all or most of the residue. The residue is a cosmetic thing only. Some case screws may be missing, or may be mismatched.
The photos here are of the actual item being sold, not "stock" photos. Please look closely at the photos, as those are the best guide to the cosmetic condition of the cabinet or case. If you'd like, you can always repaint the cabinet with readily available matte-finish black paint.
As a demo/display unit, there is no factory warranty, but there is a 30 day warranty from FatCat.Parts on items sold as New (Open Box). Warranty does not cover cosmetics, it covers only the functionality of the item. No factory packaging or paperwork is included.
On all demo/display units, what is being sold is what is seen in the photos. If it is not in the photos, it is not included, unless the listing specifies it is included.
IMPORTANT SHIPPING INFORMATION: I will ship this using UPS only. Even though USPS and other services appear as choices, you need to select UPS as the preferred shipping method. Due to the size and value of this, UPS is the only way I will ship this. Thanks.
