2m/70cm Antenna HYS-771N 15.6-Inch Whip VHF/UHF (144/430Mhz) Antenna SMA-Female for AnyTone, BaoFeng, and Yaesu

Works great, appears to be of good quality material, worth the money.

I was unable to reach my favorite repeater with the small stock antenna on my Yaesu FT-4X. After installing this antenna I was absolutely shocked at the signal strength and range improvement. We’ll worth the price paid.

Works as well as any other flex antenna. Good replacement for a dual-band hand-held radio.

Seems all short HT antennas are 1/4 wavelength on 2 Meter band ... which makes you, the holder of the HT that is transmitting part of the antenna circuit. Turns out if an 18 inch wire is attached at the base of the antenna and is left hanging down, that makes up for the missing 1/4 wavelength, turning the HT antenna into a vertical 1/2 wavelength dipole. I think the antenna makers should explain this. I got less than 1.5 : 1 SWR (which is excellent) AFTER attaching a wire that dangles freely downward. I happened to have some alligator clip leads that are 18 inch total length.For the 70CM band, it's a half-wave antenna, so the dangling wire is not needed.When testing the antenna's resonant frequency without the dangling wire on the 2 Meter band, it was coming in at around 113 Mhz, which is not good. Adding the alligator clip wire fixes that.

Good bang for the buck !!! These are a little high in SWR for the Amateur 2 meter band, but for MURS and commercial in the 2 meter band, they will work great; here you are looking at usable resonance from 152 Mhz to 178 Mhz. There is some 1-1/4 meter band resonance but too low in resonant frequency for Amateur or commercial; from 200 Mhz to 215 Mhz! The Amateur 70 centimeter band is doable from 420 Mhz to 445 Mhz and maybe doable up to 450 Mhz. However FRS/GMRS frequencies have way too high an SWR to be usable with this antenna; if you do use this antenna for this, then, proceed with caution! I have done radio work since 1975, and most handheld radios will tolerate a 3.0 SWR, some cheap ones will not, so be cautious going above 3.0 SWR. These HYS-771N are dual band, and I love the Sturdy BNC connectors, and overall they seem to be well built.For those desiring more information, I have posted my average, from three of these antennas, for resonant frequency vs. SWR. These antennas are incredibly repeatable, on the three that I checked out, for resonant frequency vs. SWR; so this tells me that they have been carefully cut and put together, and the differential between them was only about 1.3%So in a nutshell these would be good for the Amateur 2 m band, the commercial 2m band, the MURS 2 m band and most of the Amateur 70 centimeter band.I used a Yaesu YS-500 SWR and Power meter good for 140 Mhz to 525 Mhz.======================2m Band======================136.000 Mhz => infinity SWR140.000 Mhz => 5.00 SWR144.000 Mhz => 3.50 SWR146.000 Mhz => 4.00 SWR148.000 Mhz => 3.80 SWR150.000 Mhz => 3.40 SWR => Low End of the Usable Band152.000 Mhz => 3.10 SWR154.000 Mhz => 2.90 SWR156.000 Mhz => 2.90 SWR158.000 Mhz => 2.15 SWR160.000 Mhz => 1.90 SWR165.000 Mhz => 1.70 SWR170.000 Mhz => 1.50 SWR175.000 Mhz => 1.15 SWR178.000 Mhz => 1.05 SWR => High End of the Usable Band======================1 1/4m Band======================200.000 Mhz => 2.25 SWR => Low End of the Usable Band205.000 Mhz => 3.60 SWR210.000 Mhz => 3.50 SWR215.000 Mhz => 3.00 SWR => Center of the Band216.000 Mhz => 3.80 SWR => High End of the Usable Band217.000 Mhz => 4.20 SWR218.000 Mhz => 5.00 SWR219.000 Mhz => 7.50 SWR220.000 Mhz => 9.50 SWR225.000 Mhz => 11.0 SWR230.000 Mhz => 12.0 SWR235.000 Mhz => 12.0 SWR240.000 Mhz => 12.0 SWR245.000 Mhz => 10.0 SWR250.000 Mhz => 11.0 SWR255.000 Mhz => 12.0 SWR260.000 Mhz => 35.0 SWR======================70cm Band======================400.000 Mhz => 2.60 SWR => Low End of the Usable Band410.000 Mhz => 2.00 SWR420.000 Mhz => 1.50 SWR425.000 Mhz => 1.30 SWR => Center of the Band430.000 Mhz => 1.40 SWR435.000 Mhz => 1.80 SWR440.000 Mhz => 2.25 SWR445.000 Mhz => 2.90 SWR => Technical High End of usable band450.000 Mhz => 4.00 SWR460.000 Mhz => 5.10 SWR462.500 Mhz => 5.10 SWR => FRS/GMRS - - proceed with caution ????465.000 Mhz => 4.50 SWR467.500 Mhz => 4.00 SWR => FRS/GMRS - - proceed with caution ????470.000 Mhz => 3.60 SWR480.000 Mhz => 3.30 SWR490.000 Mhz => 8.00 SWR500.000 Mhz => 11.0 SWR

Perfect for Travel due to small packable size. Receive and Transmit maybe effected by wattage ratings are pretty low based on size. Flexable and light weight easy to pack , light to carry if used for mobile packing .

I live in an apartment and was able to reach the local fusion repeater 6.6 miles away full quieting at 5 watts from the inside. With my other 2 meter radio, I had to go out side to connect to the repeater. I'm so happy I don't have to go out-side during the bitter cold weather.Update: Checked SWR, 1.3:1 on 2 Meter and 2.5:1 on 440.

Tested SWR at approximately 1.2 at 446 MHz but 2.7 at 146.5 MHz when used with my CCR (cheap Chinese radio). From reading other reviews here and elsewhere it sounds like individual antennas of this model vary widely--some folks get better SWR on the 2m band and poor on 70cm. I'd be interested to see if someone purchases several and tests them all on the same radio for comparison.

Huge improvement

Does what it claims, l like the build and fit…

At this price I wasn't expecting a whole lot to be impressed with, but I was proven wrong. I'm very impressed with the performance and build quality of this antenna. Its a massive improvement over my UBC125XLT's supplied rubber duck antenna. Its performance is great over both VHF and UHF (receive only, I'm not using it to transmit).. Recommended

Perfect condition and exactly what I expected. Noticable difference from the original antenna on my wouxon KG-UVD6.

I think anything performs better than the small Uniden scanner antenna. I then bought a 12 inch (30.5cm) 25-1300 mhz scanner antenna for improved performance. I listen a lot to 2m-70cm ham repeaters on the scanner.Now I'm trying this HYS-771N antenna I found the perfomance a little (not much) better on the 2m band than the 12 inch aftermarket scanner antenna I bought. But on the 70cm band (1/2 wave) on this antenna the performance was fantastic compared to my scanner antenners and this is where the upgrade is worth it. This antenna is rated at 1/4 wave at 2m. I have a dedicated 5/8 wave 2m antenna which out performs this antenna but is much longer and might be a bit of a hassle on the go for some people. So for top performance I use this antenna for 70 cm listening and my dedicated (much longer) 5/8 wave antenna for 2m. I don't transmit so can't comment on transmission performance.Also antenna packet says also receive only modes on 120/150/300/450/900 Mhz bands which I so far havn't tried.
