## Description

Firestik K-4A Stud with Screw-On Coaxial Termination for Antenna Mirror Mounts

Review: Firestik stud - Summary: Quality component, well made, easy to install I used this in conjunction with the K40 K4018FME 18' Super Mini-8 CB Antenna Cable with Removable FME Connector Antenna cable and the Firestik SS-3H Heavy Duty Stainless Steel Antenna Spring, both from desertcart (see my other reviews). This unit is well made, installed very easy, and has performed well in my CB setup. Not much more to say. As I noted in the cable review, make sure to scratch the paint off the underside of the antenna mount that this stud bolts to in order for the CB system to work properly and avoid sky-high SWR readings. Quality of Materials: * No issues with quality Quality of Fabrication: * No burrs, rough edges, or imperfections on the stud. Ease of Installation: * Just follow directions. Make sure the nylon bushing goes on top of the mount, the stud base from the bottom through the nylon bushing, then the flat washer on top, then the split washer.. Suitability for Purpose: * Once I grounded the mount properly, my CB system using this mount has worked perfectly. Packaging/Delivery: * As usual, Prime delivers fast and delivers well. Package was brand new.
Review: Check your CB antenna bracket hole size. - Good quality, but a bit of advice is to make sure the hole in whatever mounting bracket you have is the same diameter of the threaded stock that sticks up through it. If the hole is larger, when you tighten the whole thing down, the insides of the lower portion will pull up and expose and ruin the nylon sheath inside (and it won't tighten all the way). A solution is to put a metal washer (with the exact same diameter) over the lower threaded stock before assembling. This prevents the threaded stock from coming up and allows you to be able to really tighten the whole assembly. I ruined one and had to order another.

### ⭐⭐⭐⭐⭐ Solid Product!
*by T***E on August 24, 2019*

I needed to build a small base antenna for my 10 meter radio. I didn't want to use a large antenna like an A99 so I got a K40-BCMax and put it on a small mast. I used a trucker mount and this K-4A stud mount to finish the job. I added one radial wire to the mount and this sucker really gets out! I'm talking to guys 25-30 miles out on ground wave. I wish we had better conditions to test the DX capability but still wanting.
