Nagoya 701G & 771G improving GMRS 2-way radio communications 

We shall see. ;)

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.

It is an improvement over the 1/4 waves. The downside is having to deal with another 10-12 inches of antenna.

Retevis 701? Is that the name of the antenna? I can’t find it but I’d like to look into that.

Thanks for watching!

It is a better performer than the 1/4 wave antennas. Just have to deal with a long antenna.

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. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-m75_2MyDFbM.html

Its an Argent Data Systems simplex repeater. There are cheaper solutions out there, but this one has a lot of features.

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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TSQszkFH3G4.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!

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

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

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.

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.
