Use SD7OFF for 7% off any radio
I’d love to see a final showdown with the Nagoya and all 4 Smileys. :)
We shall see. ;)
Great video and test. This is precisely what i was looking for. The 701g is conveniently short and better than the stock antenna probably on many radios on 462. The 771g is probably the biggest step up in performance but the inconvenience of a long stick.
I just received a 2 pack of the Luiton version 771g. I have to return because one is faulty but the other is outstanding. This time id rather order a genuine Nagoya. I wasnt sure if the shorter 701g would serve me better or not. It looks like I may have to buy both and swap back and forth according to the needs.
I like the Smiley collapsible 5/8 over the 771s. Didn't think I'd like it at all, but when carry/packing a higher gain antenna for those occasions, the compact size is much nicer.
I bought nagoya 701, diamond 701, brc 701, retevis 701 antennas and after doing the test the results are the best retevis 701
Retevis 701? Is that the name of the antenna? I can’t find it but I’d like to look into that.
That 771g sounds good
It is an improvement over the 1/4 waves. The downside is having to deal with another 10-12 inches of antenna.
Now I need to see the 771g vs super stick iv
Yes, it's on my list. I do think they will be close.
@@Soladaddy too many requests I know but how about the smiley slim duck vs the 701 too!
Took longer than I wanted but got all the players together in this video. czcams.com/video/m75_2MyDFbM/video.html
Good testing methods. Thanks.
Thanks for watching!
OK, I have the 771G, looks like it was worth getting.
It is a better performer than the 1/4 wave antennas. Just have to deal with a long antenna.
I also camp and am looking to use my gmrs radios around the camp. What are you using at the camper? (the black box connected to the HT on the RV A/C ?)
Its an Argent Data Systems simplex repeater. There are cheaper solutions out there, but this one has a lot of features.
Loved this!
Nagoya NA-701G what does the letter "G" represent? , I saw amazon with that same model but no G at the end of the model number... thanks
The G means its tuned for the GMRS frequencies, 462-467 MHz. The regular 701 is for the ham radio 2m and 70cm bands (144 & 440 MHz). This is the G with a SMA female end. They have the SMA male available as well. amzn.to/48jrpD8
@@Soladaddy thanks
Good day,
I'm planning to purchase either the Nagoya UT-72 or Nagoya UT-72G antenna. I'm primarily going to use frequencies between 451.000 to 455.000 most of the time, and occasionally frequencies between 144 to 145. I've heard that the Nagoya UT-72G might be a better choice since its frequency range extends from 155 to 462 compared to the Nagoya UT-72, which covers 144 to 430. However, I've noticed that the Nagoya UT-72G is more expensive in my area. Can you please provide guidance on which antenna would be the better option given my frequency usage and budget constraints? Your assistance is much appreciated. Thank you.
I consider these antennas to be upgrades from HT antennas and entry level mobile antennas. There are many better mobile antennas and they will cost more as well.
Now concerning these Nagoyas, here's the frequency ranges they claim:
UT-72G - Optimal Transmit Frequency Range: 150-165MHz, 450-470MHz
UT-72 - Optimal Transmit Frequency Range: 140-148MHz, 420-450MHz
The G model is 3% away from 144/145Mhz and covers 451/455 Mhz
The regular 72 covers 144/145Mhz and is 1% off of 451/455 Mhz.
If I still had my UT-72 I would check it on a VNA to see how it tunes to 451/455. I did check SWR on several freqs: 145, 147, 151, 154, 430, 449, 462 % 467 and it was very low for all. Here's a video with those readings
czcams.com/video/TSQszkFH3G4/video.html
Going strictly by Nagoya's claims, I would go with the regular UT-72 because it's only 1% off of 455 MHz and less than that on 451 MHz.
MY SWR readings confirm that as well.
@@Soladaddy Thank you for your detailed reply; I appreciate it greatly. The reason I've chosen Nagoya is because it offers free shipment to my country on purchases exceeding $49 through Amazon. For instance, the Nagoya UT-72 costs $34.89, so by adding another item like the Nagoya 810, I can qualify for free shipping. On the other hand, the Nagoya UT-72G, also priced at $34.89, incurs a shipping fee of $14.89 regardless of whether I reach the $49 threshold. This is why I'm considering Nagoya antennas.
Additionally, one of the main reasons I'm interested in Nagoya antennas is their suitability for camping trips. I can easily mount them on the roof of my car when my family and I go outdoor camping. I prefer not to have a permanent antenna setup.
If you have any suggestions for antennas that outperform Nagoya in terms of performance, pricing, and possibly offer free shipping to my country through Amazon, I'm eager to explore them. Thank you!
I'll look around, but I like a separate mount, could be a mag mount, so different antennas can be used. Amateur radio likes to use UHF mount connections, a few use NMO, commercial gear uses NMO connections so sticking with one type helps to allow for flexibility in using different antennas. Your frequencies are so close to US ham bands that they might be the best option.
A good jump in performance will make the antenna about twice as long so size is something to consider. I have the Tram 1180 amzn.to/49oP4n1 and it performs very well.
This antenna mount will work for speeds of about 90 kmh and slower. amzn.to/49mZjIJ or amzn.to/42LzNKF
For higher speeds, consider a larger base. I use this one and it's a little larger but I rarely go over 65mph. amzn.to/3wpkECL.
This one should handle 80MPH no problem. amzn.to/49BcAx6
If using a short antenna, say under 20" then the small mounts would work at high speeds.
These are cheaper options, smaller so less performance, but they are NMO mounts so the base can handle a future antenna upgrade. amzn.to/3UPVSFL and amzn.to/3uz186d are about the same. I would guess that these perform about the same or a little better than the Nagoyas. I listed several options to increase the chances of having something with free shipping.
These will need SO 239 to sma adaptors for HTs. Something like this. amzn.to/3uPvoJV I like the ones made with RG-58 cable over the real thin ones. Be sure to get the right SMA end for your radio, male or female.
@@Soladaddy Thank you very much for your detailed reply and for providing the link. Unfortunately, the antennas are too large, and the shipment cost ends up being roughly equivalent to the cost of the antenna itself. I appreciate your response. Many thanks!
Cant best a 771G. I keep buying supposed better antennas than Nagoyas but keep going back to the Nagoya.
For an HT used as a handheld, a 5/8 wave antenna like the 771G is about as good as it can get. Those really long antennas can pickup better, but the transmit radiation pattern can be all over the place.
Hello friend. I have a question. How did you get your other radio to retransmit your own voice to your radio? Thank you.
I used a simplex repeater that is attached to another radio. The one I use is made by Argent Data Systems. There are others that a cheaper, but this one has a lot of features. www.argentdata.com/catalog/index.php?cPath=27&osCsid=xN8Gaxw8HhqjktiEoBiak0

Whats the black box
Its a simplex repeater. This one is from Argent Data Systems. ADS-SR1 is the model.
@@Soladaddy It looks like a BTECH you have plugged into it. What cable does that combo use?
@@jehster ADS has cables for different plug types. I use the Kenwood pinout and several other brands use it as well. Waterproof radios use a different connector.
What app are you using for the mapping
Google Earth Pro.
