GRA‑RH795 SMA-Male Telescopic Scanner Antenna | 70–1000 MHz Wideband | Adjustable 7.6"–45.2" for SDR, Handheld Radio, Receiver

Really glad I picked up the GRA‑RH795! It’s made a big difference in signal strength compared to my stock antenna. The telescopic design is super smooth, and I love that I can adjust it on the fly for different frequencies. Feels sturdy, not flimsy at all, and the BNC connector snaps in nicely and tightly. When fully extended, it pulls in weak signals like a champ, and it folds down small enough to toss in my gear bag. Honestly, one of the best antennas I’ve tried for scanners, highly recommend it!

I had an old rubber antenna on my handheld scanner and it worked ok, but I wanted something more sensitive. Boy is this thing more sensitive. My radio is now stopping on noise frequencies when searching when it never did before. It really drags in the signals from all over. Because it is a hollow telescoping antenna is likely to be more fragile than some others, but with reception like this, who cares?

I bought this to test with #sdr applications in mind. I've been using the Gabil GRA-RH795 daily for the past 3 weeks with SDR receivers on my laptops, mobile phone, and HackRF One PortaPack. Cons: it's fairly heavy as antennas go, so it may put undue stress on SMA connectors or USB ports. I highly recommend using this in tandem with a short, flexible USB extension cable or an SMA pigtail jumper. It's also a bit unwieldy as you extend it beyond a few of the 10 total telescoping segments. This antenna is practically deaf below its stated 70 MHz low end, not even receiving strong CB or 10 meter ham radio signals (26-29 MHz) but I did not expect to use it below 70 MHz when I bought it. Pros: it's very wide bandwidth (70-1000+ MHz), and can extend to more than 1 meter in length, making it capable of receiving weaker signals that cheaper telescoping antennas or simple whip monopoles might have trouble bringing in. Despite being hefty, it's still more convenient than trying to use a dipole most of the time. I was able to clearly receive signals slightly outside its rated range, like ADS-B on 1090 MHz. Indeed, my NanoVNA reported a good SWR from 1000-1400 MHz with the antenna fully collapsed, so receive performance should also be good in that range. The printed frequency/length reference chart on the antenna is an excellent touch. For portable SDR use, it's small enough to keep in my kit, but it will likely only come out when I need to tune in weaker signals.

This is a great antenna to use for Receiving across a variety of bands. However, transmitting with this on VHF while fully extended is not recommended and may damage your radio. You can shorten the whip however. I found that only extending the telescoping portion of the antenna around 8.5 inches results in a low (<1.5:1) SWR. Fully extended, the SWR is about 16.5:1, which absolutely could destroy your radio. Nonetheless, should be a great all-around Receive Only antenna and I will keep it for that capability for my SDR purposes. Use something else better matched for Transmitting, or plan to carry your SWR meter and adjust its length to tune as needed.

Works Fine....

This is a great antenna!

The antenna separated after a few weeks. I unusuable now and damaged my scanner

I purchased this for my Uniden Bearcat and it works great to receive airband signals. BNC adapter connects with no issues. The length of this antenna when it is fully extended is also insane.

Tengo muy buen alcance en la banda aérea (+-7 KM) y muy buena recepción en las bandas VHF y UHF, la antena es larga y no es tan frágil, buen alcance incluso totalmente retraída. Es una muy buena opción para sustituir en Scanners Análogos; desconozco y funcione correctamente con trunking o señales digitales.

I’ve been using this product for a few weeks now and I’m genuinely impressed with its performance and quality. The build is solid, it works exactly as advertised, and the setup was quick and hassle-free. The value for the price is outstanding, making it a smart choice for anyone looking to upgrade their toolkit or start a new project. I’ve tested it in multiple scenarios, and it consistently delivers great results. Whether for a hobby project or a more professional setup, it has earned a permanent spot in my collection. Highly recommend for its reliability, ease of use, and excellent value!

Have not noticed any additional improved signal strength with this model antenna.

A fabulous all-band scanner antenna featuring 8-sections and a handy diagram showing how many sections to use for which band. Japanese quality reminiscent of the 1960s and 1970s.
