RF Connectors and Adapters
Max-Gain Systems, Inc. (MGS) is proud to offer a new line of the most popular types of RF adapters to our customers at very reasonable prices! After a long search, we have located a producer whose quality we were satisfied with (no small task at a reasonable cost) and we have become direct importers of these lines.
Unlike most sellers of adapters, it is actually EASY to locate the adapter you need. Our adapter catalog page is cross-referenced, and contains PHOTOS of all adapters if you "aren't quite sure what it is called".
Your satisfaction is always 100% guaranteed. If not satisfied for any reason whatsoever, just email for a return authorization, return connectors to us prepaid, and your purchase price will be immediately and cheerfully refunded. All you ever risk is shipping. Ask about price breaks for quantities, as well as wholesale pricing for resellers!
Our catalog lists each adapter both ways....for example: the very popular stock number i330, (pictured above) is listed both under the "N" male adapters and under the UHF female (SO-239) sections. Simply pick either end of the adapter you want, look under that section, and quickly find your adapter. Still in doubt about what you need? Just view the product photos below or click on the stock number listed below to quick jump to the photo area! It's very hard to mistake what you want that way!
Don't see what you want? We WILL be increasing our lines, but wish to see what our customers need first, so if you need one that we currently don't carry, email us with a discription of what you want, and we will consider it for our next shipments.
Types: There are many different types (or series) of coax adapters and each is designed for a specific purpose and application. Frequency, power, and impedance ratings often vary between these types.
Gender: Most coax adapters are male-female gender; however, some coax adapters are unisex such as the HP 7mm, Amphenol APC-7, and General Radio GR874 or GR900.
Frequency: The frequency range of any coax adapter is limited by the opposing side of the adapter. For instance, if one end of an adapter has a SMA configuration (~18GHz), and the other end has is BNC (~4GHz), then the adapter must be de-rated to the maximum frequency of the side with the lowest frequency rating. Therefore, in this example the SMA to BNC adapter will have a maximum frequency rating of 4GHz. Use the tables below to see which types may be most suitable for your use.

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.

On the lower right are four of the silver plated UG-176/U size reducing adapters (fits RG-59 and RG-8X coax). No adapter/reducer is necessary if using RG-8 coax or LMR-400. A US quarter dollar coin is included for size reference.
