Review: The best antenna I have, it works as a champ. - Hardly ever leave a feedback of this nature but so far I stroke a good one. This is a must try at least for me. I bought it for GMRS base station, the antenna came as advertised with two U bolts, screws and washers that I didn’t need as my goal was to get it as high as possible. I cut a thin rope 15 inches long and put 2 inches down on each side of the tip cover about 180 degrees from each other and with electrical tape went to town and got it secured and cross taped, (just in the tip) no kidding. Then connected a lighting arrestor between the antenna and the 25-30 feet of R-213 cable in running to the shack. It’s true the antenna has a short tread connector and so one end of the lighting arrestor so it was perfectly tight and matched, the I put more electrical tape between the arrestor tip connecting to the bottom of the antenna so it’s (secured as heck). Also grab two metal hangers made them straight cutting 18 inches on each hanger making them as straight as possible. Then I twisted one metal hanger with a pair of players around the arrestor and base of the antenna and made them as straight as possible again follow by doing the same thing with the other metal hanger creating a 4 leg ground plane 90 degrees aprox from each other ( didn’t turn out perfect but it worked). With a sling shot and fish line attached to a hex socket shot the line about 32 feet over a tree branch and when the line came down I attached a cheap 4 dollar 75 feet harbour freight poliethelie or polipropelyne line. Then I cut enough slack to tie somewhere and attached the antenna by the tip rope with the new line and got it hoisted like a flag 29 feet up in the air just 1-2 feet short of touching the branch. Finally got the nano VNA set on S11 and set to measure 462-468 MHz and the highest SWR obtained was 1.35 to 1.00 on 462Mhz and1.07 to 1.00 on 468Mhz. Connected the cable to my GMRS transceiver and hit 17 miles on simplex and 26 miles to a repeater as of now. With excellent reports the Radio puts out 25 watt on max power. Looking for more distant GMRS users and repeaters to try again. I previously used the Nagoya 771 above the shack and 6-7 miles was the best I could get on simplex and no repeater look because my voice came scratching.
Review: tunable to a lower SWR on GMRS, when fiberglass tube cut at the top to access antenna - I bought one of these after I was able to talk on GMRS simplex to a friend 10 miles away (30w on my radio, 40w on his) who mounted one of these on a 20ft flagpole. I found them to be between 1.6:1 on 462mhz to around 2.0:1 on 467mhz out of the package with no ground plane. Using a PVC pipe cutter (***Be sure to wear gloves and an N95 to avoid exposure to any fiberglass fragments from cutting***), I cut the first 2 inches off the top, only to see the tip of the radiating element (actual antenna whip) to be just below this. I cut just a bit more until I got to the radiating element and in very small increments using a wire cutter and antenna analyzer (you could do this on very low power, using an SWR meter and a Baofeng programmed in 1Mhz increments on simplex from 450 (antenna longer)-468Mhz (Antenna shorter)) I was able to trim it just enough to get it to 1.28:1 on 462-463Mhz and 1.7:1 on 467-468mhz. Adding a $14 SO239 ground plane (There is a $40 version of this that comes with the ground plane kit) I found the antenna to go down to 1.14:1 on 462-463mhz and 1.44:1 on 467-468mhz when also mounted on a metal pipe. It was showing on my antenna analyzer as having a flat SWR match (1:1) at 459-460mhz). I didn't want to chance cutting it too short and left it at this SWR match for GMRS use. To cap it off, I used some heat shrink tubing over the top 1 inch of the tube, which made a small PVC cap fit snug over the tube and cemented it in place using PVC cement. I was able to make a simplex contact on 462.725mhz with a friend who was himself, 10 miles from me with full clear audio on the version of this antenna I tuned to GMRS and vice versa. I as well was able to reach a repeater that is around 60 miles from me (Northwestern Broward County to Homestead, FL with line of sight across the Florida Everglades). I had this antenna mounted on a temporary deployed, fiberglass telescoping mast that was extended to 30 feet, using LMR-400 coax). For a very low cost base station antenna, this will perform. Just know it is not a high gain antenna, it is a that factors such as type of coax, height and location the antenna is mounted can improve or lower the performance of this antenna. At the right height and properly mounted, you should get very good results on GMRS repeaters in a 50 mile radius and base station to base station on GMRS simplex, I expect this to give you at least 10 miles, probably as much as 30-40miles if mounted on some elevation with line of sight over the horizon. Base to mobile, I would expect this to at best get you around 5-10 miles, depending on terrain (flat vs. mountainous). If the manufacturer were smart, they would make the cap of the antenna removable (screw on?), so the user can tune the antenna for their needs. None the less, those who are not tech savvy, the SWR across GMRS out of the package is still adequate for local repeaters that keeps your radio happy, just don't expect alot of performance from it..

## Questions & Answers

**Q: Does antenna need to be grounded?**
A: The antenna does not need to be grounded, You can also add an additional ground plane kit to it, ground plane kit will enhance the signal strength and efficiency

**Q: Is the SWR of the antenna to be less than 1.5?**
A: Antenna tested by a comprehensive measuring instrument, the SWR of the center frequency conforms to the technical parameters (less than 1.5), Your test need to eliminate interfering factors such as test frequency, antenna installation, feeder line

**Q: Can it be used indoors?**
A: Yes, it can be used both indoors and outdoors. It works for indoor use in places like attics and garages

### ⭐⭐⭐⭐⭐ Excellent value and quality and performance
*by G***R on October 20, 2025*

Very nice GMRS antenna. Talked long distances on this antenna over 60 miles every day to a local repeater. I have bought two and will probably end up with a few more for different purposes. Go ahead and buy one you won’t be disappointed would recommend. Also consider adding the ground plane kit. 73’s 🤓
