The PL-259, or UHF male is by far the most-used RF connector, and Max-Gain Systems, Inc. is proud to offer our top quality (solid machined brass body, silver plated body and center pin, and Teflon dielectric) PL-259's at EXTREMELY attractive pricing! We sell single piece, or large quantities . ***DEALERS: inquire about wholesale pricing on our entire, WIDE line of connectors and adapters! ***
Teflon Dielectric PL-259
MGS is proud to offer these brand new, solid brass body, heavily silver plated, teflon dielectric PL-259 (type UHF male) connectors for sale, as well as silver plated type UG-175 and UG-176 adapters. They are of excellent quality. We have used these ourselves for years, and find that they take solder beautifully, and the teflon will withstand very high temperatures with no problem. The photo shows several of the PL-259's in various orientations.
Max-Gain (before plating) PL-259
The best body material is brass (some are tin or aluminum or zinc, but ours are of course brass). The best plating is silver, the lowest resistance electrical conductor, and one that takes solder like a wick, even without flux. Nickel plated connectors can be quite difficult to solder, even with a good flux. Many PL-259 connectors of inferior quality have the center pin come completely out when heated during installation. Even some that are represented as having "teflon" dielectric. Worse, some with low temperature plastic dielectric will actually melt!
Max-Gain PL-259 Prototype Testing
During our testing of prototypes, we "torture tested" our PL-259 connectors with a blow torch ( DO NOT TRY THIS AT HOME! PTFE / Teflon gives off many harmful gases if super heated!) After being super heated, the center pin was tapped on with a one pound hammer till the center pin glowed red hot and the center pin stayed true, the dielectric stayed completely unscathed, and the connector continued to perform without flaw.
PLEASE NOTE: We sell all of these connectors individually, NOT in pre-packaged "packs of 10". You will get the discounted pricing if you order 10 or more quantity in each type. For example, if you wish to order 10 of the PL-259's, order as quantity 10 of stock # i500 on our order form.. NOT as quantity 1.
PLEASE NOTE: For the convenience and reference of our customers, we have prepared an installation and soldering guide with step-by-step instructions and photographs showing how to install BOTH our PL-259 connectors and our new type N male, cable end, 2 piece connectors. The type N 2 piece (our stock # i303) is an easy to install N male, which installs much like the PL-259. We hope you will find these guides helpful!

We can ship adapters very economically via USPS (priority post, small flat-rate box). There is no weight limit for US shipments. anything that will fit in the box (even up to 80 of our PL-259 connectors!) ships at the flat rate, which is very reasonable (check USPS.com website for current rates) plus a flat packing charge of $2.00 per order. This method has a 4 pound weight limit for foreign shipments. We supply delivery confirmation on Priority Mail shipments to USA addresses at no extra charge. We also ship via FedEx ground, and $100 in insurance (and tracking) is provided at no extra charge. FedEx ground is best option on heavier shipments. We will be happy to quote shipping cost before shipping your order if you tell us to. International customers inquire for shipping options and quotes.
Duties, customs charges, VAT, and / or brokerages fees , (if any might apply for your country) are impossible for the shipper to determine, and are ALWAYS the responsibility of the purchaser. International customers agree to pay any and all additional charges that may be billed to cover these items.
Max-Gain Systems, Inc. Soldering Guide
SOLDERING PL-259 (our stock # i500) and
Max-Gain Systems has sold PL-259 connectors for many years. We have been asked countless times about the correct way to install these connectors on various types of cables. Here we address these questions in a comprehensive installation and soldering guide. We hope you find it helpful!
PL-259 connectors are used in an extremely wide range of applications due to the versatility of this connector and ease of installation. It is by far the widest used series at frequencies under 400 mhz. There is, however, an equally wide range of quality (or lack of quality) in the PL-259 connectors that are available.
The best body material is brass (some are tin or aluminum or zinc . ours are of course, brass). The best plating is silver, the lowest resistance electrical conductor, and one that takes solder like a wick, even without flux. Nickel plated connectors can be quite difficult to solder, even with a good flux. Many PL-259 connectors of inferior quality have the center pin come completely out when heated during installation.. Even some that are represented as having "teflon" dielectric. Worse, some with low temperature plastic dielectric will actually melt!
During our testing of prototypes, we "torture tested" our PL-259 connectors with a blow torch (do not do this at home . PTFE / Teflon gives off many harmful gases if super heated!) After being super heated, the center pin was pulled with pliers and the center pin stayed true, the dielectric stayed completely unscathed, and the connector continued to perform without flaw.
Max-Gain Systems, Inc. has all of our connectors made to our own specifications and will never sell anything less than the highest of quality. Our PL-259 connectors have a solid brass body with silver plating and a silver plated brass center pin. Our PL-259 connectors also have only the highest quality PTFE ("teflon") dielectric. These high quality connectors will serve you well in whatever application you choose to implement them within their rated range of operating frequency.
When soldering PL-259 connectors the first step is to make sure you have all of the tools necessary to complete the job. The tools we recommend include:
Once you have acquired the necessary tools for the job then you can proceed to the next step of your PL-259 connector installation which is determining the coaxial cable type that will be used and the size adapters that may be necessary with some cable diameters.
1. Connectors / Adapters and Coax / Cable
2. Soldering PL -259 connectors with the "UG" adapters
First cut your cable to the desired length for your application. Once the cable is cut, make sure to put the sleeve of the PL-259 on the cable first, with the knurled end of the sleeve closest to the tip of the connector. Second, put your UG-176 adapter on the cable, with the larger, blunt end pointed away from the cable end. Next, simply strip back the black outer insulation ¾ of an inch (FIG 2-1). Once the outer insulation is stripped back, cut through the braid and dielectric exactly ¼ of an inch from the end. Take care not to cut or nick the center conductor (FIG 2-2).
Leave at least an 1/8 th of an inch of the dielectric protruding from the braid fold (FIG 2-4). This helps prevent accidental shorts during the screwing on of the PL-259 connector to the UG adapters.
Now that the cable is prepped, the adapter is ready to be screwed into the PL-259 connector. Grip the adapter firmly and also grip the PL-259 connector body. Hold the adapter still and screw the PL-259 down over the adapter. You may find pliers helpful to do the final tightening, taking care not to scar the connector finish. Your ending product is a PL-259 connector prepped and ready for solder (FIG 2-5).
Now we begin soldering the PL-259 connector and the UG adapter to the cable. Before beginning soldering, you should always check resistance from the center pin to the body with an ohmmeter in a low resistance scale. After verifying that there are no braid - to - center pin shorts on the other end of the coaxial cable, you should see infinite resistance (open). If not, you probably have allowed a stray strand of braid to touch the center conductor or center pin, and this must be corrected before soldering.
When this is completed, as a final test, you should always check resistance from the center pin to the body with an ohmmeter in a low resistance scale. After verifying that there are no braid - to - center pin shorts on the other end of the coaxial cable, you should see infinite resistance (open). As a final check, inspect the tip of the center pin to be certain that there is no excess solder present that could interfere with easy insertion of the tip of the PL-259 into the female (SO-239) connector. If there is a tiny bit of excess solder present, it can usually be easily removed by lightly scraping the soft solder with the edge of a knife blade until smooth. This completes your PL-259 installation, and the connector is ready for use!
