10 pieces of PL259 connectors

Note: Installation requires soldering the center conductor

Mechanical

By design, all connectors in the UHF connector family mate using the ​5⁄8 inch 24 tpi threaded shell for the shield connection and an approximately 0.156 inch-diameter (4 mm) pin and socket for the inner conductor. Similar connectors (M connectors) with an incompatible 16 mm diameter, 1 mm metric thread have been produced, but these are not standard UHF connectors by definition.

Surge impedance

UHF connectors have a non-constant surge impedance. For this reason, UHF connectors are generally usable through HF and the lower portion of what is now known as the VHF frequency range. Despite the name, the UHF connector is rarely used in commercial applications for today's UHF frequencies, as the non-constant surge impedance creates measurable electrical signal reflections above 100 MHz.

Virtually all of the impedance bump and loss is in the UHF female. A typical SO-239 UHF female, properly hooded, has an impedance bump of about 35 Ohms. The length of the bump is typically ​1⁄2 inch, where the female pin flares to fit over the male pin. This bump can be mitigated by using a honeycomb dielectric in the female pin area. Many VHF/UHF amateur operators use special UHF females that maintain a 50 Ohm surge impedance.

Used to connect cable with PL-259 connectors, or can be used to change PL-259 male to SO-239 female

Connect 2 coax cables with the barrel connector

Lightning Arrestor Connector PL259(UHF male) Plug TO SO239 plug(UHF Female)

• Coaxial Lightning Arrester,Freq:DC-3GHZ
• PL259(UHF male) Plug TO SO239 plug UHF Female)
• Lightning surge protector for Coaxial cable.
• The Lightning Arrester protectors offer HF/VHF/UHF other frequency equipment with extremely low loss. They boast an insertion loss of less than 0.1 dB.
• Arresters should be installed as close a possible to the equipment to be protected, often at the point where the coax cable enters the building. They can also be installed near the antenna for additional protection.

It is a great lightning protection solution for 2G, 3G, 4G,HF,VHF,UHF and LTE service as well as 2.4 GHz Wi-Fi, 900 MHz, Ham radio and other lower frequency Antenna. This model features PL259(UHF male) Plug TO SO239 plug(UHF Female) to be used inline. This protector will pass DC, so it is suitable for applications where DC is carried through the coax cable. Both connector ports of this unit are equally protected -- it can be installed in either orientation. A ground lug and terminal on the housing provides superior grounding.
