Product Description

ANT-234-002 UHF Coax Lightning Arrester

Proxicast Pro-Grade Coaxial Lightning Arrester for 0 to 3 GHz (UHF-Male/UHF-Female)

230V Discharge Voltage for Maximum Protection

This gas discharge tube lightning suppressor features wide-band operation from DC to 3 GHz with low RF insertion loss, making it ideal for HF, Marine VHF, UHF, CB, Amateur Radio (Ham), P25, GMRS, LMR, Two-Way and other radio system antennas. It absorbs 2.5 times the energy of 90V arresters.

UHF-Male to UHF-Female In-Line Arrester

With UHF-Male (PL-259) and UHF-Female (SO-239) connectors, the arrester connects inline with your existing coax cabling. It passes DC for applications such as remote amplifiers and LNAs. Both ports are equally protected - it can be installed in either orientation. The housing ground lug provides superior grounding.

Protect Equipment, Structures & Personnel

Coaxial lightning suppressors should be installed between outdoor antennas and radio equipment to protect from high-energy electrical pulses carried through the coax cable either from a direct or nearby lightning strike. Arresters should be installed outdoors as close as possible to the equipment to be protected, typically at the point where the coax cable enters the building.

Key Features

  • Bi-Directional Operation
  • Wide Band Frequency Range
  • 230V Discharge Voltage
  • Replaceable Gas Discharge Tube
  • Corrosion Free Nickel Plated Brass Construction
  • Low VSWR & Signal Attenuation
  • Grounding Lug

Pro Installation Tips

Be Safe!

  • Install arresters away from combustible materials.
  • Weatherseal the coax connections to the arrester.
  • You must connect the ground screw of the arrester to an earth ground such as:
    • The ground rod tied to your building's electrical panel.
    • A water utility pipe that enters the building.
    • A new copper ground rod that you drive yourself.
  • Use #10 AWG (or thicker) copper ground wire between the arrester and ground point.
  • Consult your local building code for other grounding and safety requirements.

UHF UltraFlex Coax Cables

The wrong cabling can wipe out antenna gain. Use only low-loss 50 Ohm coax like our ANT-141-034 series ultra-flex cables available in multiple pre-made lengths.

J-Max Antenna Mounting Arms

Proxicast's professional grade ANT-800-JP3 J-Max adjustable antenna mounts feature extraordinary strength and premium materials. Available in stainless steel and rust-proof aluminum, these mounts will last a lifetime.

Coax Weathersealing Silicone Tape

If moisture gets into the cabling it can create intermittent shorts and permanent damage. Seal all outdoor connections with our ANT-900-002 Pro-Grade Coax Silicone Sealing Tape.

Hope it works
Installation was very easy and took only minutes. I put it near the ground rod so running the ground wire was no big deal. I have no way to test how much DB loss I am getting but my repeater seems to working as it should.I just hope this thing works if lightning does strike. I hope that doesn’t happen but if it does I’ll be sure to update this review.

Color: F-Male/F-FemaleVerified Purchase
Quality: Well made, solid construction. The F-style connectors fit the existing RG-6/U cables with no problems. The grounding connection was well designed and easily attached to #6 copper wire.

Functionality: The arrestor was placed between the outside antenna cable (75 ohms) and at the coax distribution to the house. The ground wire was connected to the main house ground. Both UHF and VHF digital TV channels did not appear to have any reduction in signal. Will report back when and if there is a lightning strike near my antenna.

Would have given 5 stars, but will reserve that honor until there is a lightning strike near the house.

Color: F-Female/F-FemaleVerified Purchase
Excellent quality, well finished, and the grounding lug is sturdy. I ended up buying two more.

I also bought the replacement cartridge package for future protection in case I do get a strike (likely on our 35' antenna mast here in Florida). Hopefully I'll never need the spares but wasn't sure if they're a standard replacement part that will be available far into the future or somewhat hard to come by. Do some research and that extra might be unnecessary if it's an industry standard spare.

5.0 out of 5 stars Easy to install protection for coax connected electronics
Reviewed in the United States on April 27, 2024
Color: F-Male/F-FemaleVerified Purchase
This is a professional lightning arrester which is easy to install and has replaceable gas tubes so if in blows to protect the equipment, it can be put back into service with a new tube.
The only problem I had was not with the product but with big A. Ordered the correct product and was sent the wrong one not once, but twice! Resorted to communicating directly with Proxicast who took back the incorrect item and sent the correct one. Tried to tell big A what the problem was but it didn't work.

5/1/2024 Update:
Received the correct unit from Proxicast which was nice! Out of curiosity, I opened the port where the replaceable gas tube is located. When I did, it looked like there was no tube in the unit. Contacted Proxicast to let them know along with a picture of the missing tube. Right away, they apologized, said they would look into the problem, and sent some replacement tubes right away.
After examining the picture I sent, they determined that the gas tube had actually fallen inside the unit so it was not missing after all. Since I didn't know what I was looking for and saw the empty hole, I assumed it was missing. I was able to retrieve the tube (not very easy) and now I know what can happen if you are not careful how you open it up.
I have since suggested possibly some kind of plastic insert to keep it from falling into the unit or a "read me first" to warn of the possibility of the tube falling inside the unit if not opened carefully.
Though I have offered to return the replacements, Proxicast has said I could keep them.
This is -top notch- customer service which is very refreshing to find in a company where many would have ignored the problem all together.
The take:
If you need to remove the gas tube from the unit, place the unit on a flat surface with the port facing up and be aware that it could possibly fall inside the unit.
This is a vendor you can trust that supplies a very good product and will respond to you if you have any problems.
Buy this product if you need a good lightning arrester for your satellite cable feed.

5.0 out of 5 stars Essential safety devices
Reviewed in the United States on February 4, 2024
Color: UHF-Female/UHF-FemaleVerified Purchase
I purchased both the female/female and male/female versions to use in the field with portable antennas mounted on grounded tripods (I use a 4-foot spike, driven about 2 ft into the ground, with grounding clamp, whIch I also connect to the arrestor). Both units are well-made of premium materials. Neither had any measurable effect on SWR on two different antennas (a vertical J and a 5-element yagi). Cannot speak to intended function (would require a lightning strike....) but I very much like the replaceable gas discharge tube. I found these replacements via a Google search (they are available in two forms -- be certain to get the ones that do NOT have wire connections). For convenience and to avoid confusion, I would recommend that the seller include an Amazon listing for replacement gas discharge tubes in their Amazon store. These are devices that come under the category of 'better to have it and not need it than need it and not have it', kinda like an insurance policy.... Very happy with these units....
