Questions & Answers
According to Amazon, it has a maximum power of 10 watts, but Baofeng puts the figure at 5 watts. Which of the two is proper?
I DON'T KNOW WHICH IS TRUE. There is a maximum power output of five watts from the BaoFeng radio. An antenna such as this has a maximum power rating of 10 watts. You can still use this antenna to receive signals from a BaoFeng radio that transmits at 5 watts, but if you want to connect it to another radio that produces up to a 10 watt frequency, it will work fine. If you raised the antenna any higher, the radio would fry.
Wouldn't it be better if we used a better antenna?
Would you use a whip for that? It isn't like that at all. There are other types of people If yes, then I would agree. My favorite is a Nelson Slim Jim. String it up in a tree ten feet high, and I can hit a repeater 60 miles away with a 5 watt transmitter I'll be back in 9 minutes (that's perfect) By using this 771 whip, I can hit a repeater 30 miles away with the It doesn't matter where you're at, but I live in Florida and the higher the antenna, the better our reception will be (less interference from trees and buildings). An antenna that focuses signals in one direction is called a beam antenna. The 3 el handi that I use to pick up AMSAT chatter is my 3 el handi. As a result, the word "best" is simply suitable for the job. On my UV-meter I have an antenna like this Unless I'm backpacking or tracking, I use 5RTP. The one I'm liking the most is the one I used to use.
When the antenna is fully retracted, do you think it is safe to transmit? Is it safe for the radio to be exposed to it?
This equation can be used to determine the length of an antenna This has been formulated as follows 2808 / frequency = length in inches You can conveniently retract the antenna down to a length of only 4 inches when you are just receiving data, not transmitting. This means that the only frequency with a SWR of 1 is A 700 MHz signal is represented by number 1. In this case, if you extend the length to as much as 6 inches, it will be clearer. There are 3" more than you could TX It runs at 440 Mhz, but that's all. You need to make the length 12 instead of 10. There is a 7" slot for 220 MHz. The dial should be set all the way up to the 16" mark for 175 MHz. You'll still be under the 3 if you do that There is a 1 SWR requirement for 2M at 146 MHz. If you want to get to 19 inches, you need to lengthen it. Two inches. The antenna cannot be used for Ham radio transmissions, so it isn't suitable in any practical sense. You could even use the MARS applications that operate at 150 MHz.
Do you consider the retractable version a good or a bad thing? Is it true that the reviews are mixed?
As for the antenna I received, it was not retractable, but the one I have works seamlessly. This is a very limber non-retractable chair. It stretches quite a bit and isn't so out of shape that it won't flex quite a bit as well. The value of using an antenna such as this would be diminished by any retractable antenna. When you need to have a short antenna, then go ahead and buy one, they are cheap and I have multiple antennas for a variety of For example, I use a short rubber duck if I'm working a festival with a base station nearby and a repeater is not readily available, or I use simplex when I'm traveling. Whenever I need something like this, I use it. If you want to buy a nonretractable, I recommend you do so.
Selected User Reviews For Authentic Genuine Nagoya NA-810 2.5-Inch Mini-Whip VHF/UHF (144/430Mhz) Antenna SMA-Female for BTECH and BaoFeng Radios
This antenna was terrific on price
I have owned it for about a week and have done some SWR testing on it while connected to a Baofeng BF-12 This 8 watt radio is the F8HP. With my Tacoma, I just threw the antenna on top and tested it in less than ideal conditions, in a suburban neighborhood with lots of noise and clutter. The photo shows that even at worst, it was at 1 MHz on the 70cm UHF band, but at the top of the band it was at 14 MHz. Readings were typically below 1 for most of the measurements. The most excellent reading is number 5, which is considered by most. My garage is not damaged because I accidentally backed into it without unscrewing the magnetic base. I have driven up to 70mph and it hasn't budge all this time.

After becoming interested in a hobby, I tend to buy multiple Baofeng VHF/UHF handheld two-way radios over time
My interest in FRS/GMRS walkie talkies ultimately led to the purchase of multiple Baofeng handheld two-way radios There are BTECH AMP-equipped radios and a two-way radio A mobile amplifier of the type U25. The first time I bought the UT-I was from Nagoya A 308UV magnetic mount car antenna that worked pretty well when directly connected to a BaoFeng BF-100 This is the first of two F8HP formats It was originally a two-way radio, but was upgraded to this one A super loading coil measuring 19-inches in diameter With a PL-style connector, this magnetic mount VHF/UHF antenna measures 15 inches The AMP- 259 male connector mates with the AMP- 259 female connector Throughout U25's video you can watch a video of the SD There is a female connector 239 in this It was amazing how this upgrade turned out! Despite the remarkably low SWR, the difference in quality, power handling, and, most importantly, the power to weight ratio was striking. Measured over 2 inches, the UT308UV measured over 2 feet. RF power can be radiated from the transmitter with only a 5 SWR in combination with just under 15W of power. I'm sure you already know this, but The measured SWR had been reduced by one with the 72 super loading coil antenna. The amount of power delivered by this unit is almost 20W. The UHF amplifier has greatly improved, not just in terms of safety, but also in terms of power delivery. A Nagoya University-Atlantic UT-Analysis A super loading coil measuring 19-inches in diameter Magnetic mount mobile antennas for VHF/UHF are often considered the best antenna for inch setups. This book is highly.

There is no problem with this antenna
The GMRS market has been waiting for this antenna for a long time. A big problem with most GMRS and FRS radios is that the antenna is permanently fixed to the transceiver, which causes large signal losses, since if you transmit in a vehicle, the vehicle is absorbing a large amount of the signal. 100% of the signal can be radiated in the clear with the Nagoya antenna There have been no cable losses except a few minor ones. It is much easier to receive. If you have a couple of these antennas and a line of sight, you can easily make 60 - 80 miles There are 70 miles between these points. - There is also another important thing to note. Magnets on the antenna base are powerful enough to hold up on any vehicle roof, no matter how fast it is going. It is covered by a rubber pad, so no damage is caused to the roof.

A minivan's worth of cable is attached to the computer
I love it. I have a cable that is long enough to run from the back of my mini van Material is very durable, and when I'm on the autostrada, I can drive at speeds up to 90 miles per hour without it moving. There is no issue with the reception at all. My husband and I installed it in less than 5 minutes. We're so happy with this product that we can't even believe it.

Everything appears to be in order
It has a sufficient length of cable, split connectors, and a reasonable storing magnet (could be a bit stronger, but at least it does not hurt the paint). Having not been able to provide technical performance details except for the fact that it was possible to make contacts over a reasonable distance using a Baofung 5v transmitter.

There is a problem with the 259 connector
In the first place, the PL-I There was a problem fitting the antenna coax connector into the PL-259 On the SMA adapter, there is a female connector 259 . A little mess was made by whoever soldered the connection. To clean the female end of the drill bit, I used a #20 drill bit. It only took a little bit of emery cloth on the male end for it to be more comfortable. The 2M SWR was 1 out of the box There was 1 CM SWR on the 70CM. It is strong but not so strong that you have to be concerned about scratching the paint when you take out My rating of durability dropped from 4 stars to 3 due to the lack of durability of the SMA adapter. I will work on It would be helpful to a friend to use this antenna. Currently nothing has changed as of September 21st.

Antenna seems to work well
Compared to Diamond and Comet, this is a good price. This is a nice antenna, which I bought two. I have two sets of headphones, one for my mobile phone and one for A hat was bought by me.
The antenna is solid and very sturdy
Despite being thin and flimsy, this antenna is very sturdy and gives me excellent range on my This handheld transmitting receiver (HT) is compatible with F8HP handheld receivers. I won't have to worry about it blowing off my car when I'm driving down the road at 60 mph since the material is thick and strong. I like the build quality and the extra line for the feed lines as well. It was the best purchase I could have made.
