Don't forget that he has 1998 reasons why Midland and Wouxun radios are total junk. Or are we up to 4995 reasons now.

Again it is going to depend on your location, terrain, amount of trees and buildings, etc. More realistic simplex range for 70cm and GMRS is going to be 2-10 miles, again depending on your surrounding and location. We have guys check into our weekly 2m simplex net from as far away as 55 miles straight line. They definitely are using beam antennas up high on towers and there is a good chance they are also running amplifiers too. I know we do have guys that check into the 2m simplex net that are 40-45 miles away and they are not using any type of amplifier and they are using vertical antennas. Again location and height of the antenna plays a key part on how far one can be heard. My dual band antenna is a GP-9 with the base at 22 feet above the ground. The farthest I have talked to anyone on 70cm or GMRS using my 50 watt mobile radio on a simplex channel/frequency to another using a base station with a vertical antenna at least 30 feet above ground has been about 25 miles. But that is pushing it. I use a short Comet SBB-1 NMO dual band antenna and a short Tram 1174 antenna tuned for GMRS on my Ford Escape. Now talking to someone 18-22 miles from my base radios to their base radios is normally not a problem when using 70cm and GMRS. There are a lot of variables on how far you can get out using VHF/UHF such as type of antenna, antenna height, your location and local terrain, etc. To answer the original question, you won't get out any farther using the 70cm amateur band compared to using GMRS when the radios and antenna setups are the same as far as power output and antenna height.

Yes one can use an amplifier on 2m and 70cm. But comparing apples to apples by using a 50 watt 2m/70cm mobile to using a MGRS 50 watt mobile, then there will not be any difference in the range with 70cm and GMRS.

We have our 70cm repeater antennas and GMRS repeater antennas on the same tower. The 70cm antennas are higher but the actual range is the same for both GMRS and 70CM. We get between a 30-35 mile coverage radius with the usual dead spots due to local terrain. Our 2m repeater antennas are at the same height as our 70cm antennas and we get a 80-85 mile coverage radius with it. Those ranges are all with using 50 watt mobile radios and good mobile antennas with the proper ground plane. And before "some people" state how they get 200 + miles with their GMRS radios, they live in the most perfect ideal location across wide open and flat desert terrain. Real world range will be anywhere from 15 miles to 50 miles depending on what part of the country you lie in and what the local terrain is like.

I have two KG-1000G radios along with one KG-XS20G. I have not had any issues with all three radios. The XS20G is a very nice 20 watt radio and easy to program through the radio or with a computer. Actual output power ranges from 18 watts to 25 watts. It also has the same screen and menu setup as the KG-935G hand held radio. The plus of the KG-1000G is that it is 50 watts and has a removable faceplate. That makes it nice when space is limited like in most new vehicles. It costs close to the same as the Midland MTX500 and MTX575. I have used all three and prefer the KG-1000G. A lot of people are happy with the Radioddity DB-20G. SO that is another option for you.

Many HF antennas were made with twin lead wire from Radio Shack. And I still have a great set of Radio Shack Realistic speakers that still sound great after 40+ years. I have to agree with @SteveShannon, I would rather use a good quality 75 ohm coax over some cheap craptastic 50 ohm coax. I don't even like using the cheap Amazon or eBay coax for short jumpers even though loss is not a factor with such short lengths. The biggest issue I have is the lack of shielding in the cheap stuff.

One of the main differences between cheap coax and more expensive quality coax is the amount of shield braid used and also the materialist is made from. You will only see about 50-60 percent of the dielectric being covered by the shield braid on cheap coax where you will see 70 to 100 percent coverage in the more expensive coax. The amount of shield braid makes a difference in how it protects against RFI and will also act as a better counterpoise when the coax is used as such. It is common to use the coax as a counterpoise when using end fed half wave antennas for HF versus running a separate counterpoise wire.

I reran the numbers using RG-58, RG-8X, and RG-8 with the length of 15 feet since that is the average length used in vehicle installations. RG-58 RG-8X RG-8 Now most mobile antennas will not have 5 dBd of gain so you will have to adjust that number using the calculator.

I ran the numbers using the https://kv5r.com/ham-radio/coax-loss-calculator/ for several types of coax. Here are some screen shots showing the losses for 100ft of coax. LMR400 RG-8X RG-8 1/2" Heliax

I've tried the Nagoya 701G and 771G on my KG-935G and the stock Wouxun antenna performs better. I do see an improvement when using the 771G on my Baofeng UV-5R GMRS radios.

I do wish that Wouxun would include a way to adjust mic gain in their radios. And yes the KG-1000G mic is on the hot side. Another thing that greatly helps is holding the mic at an angle to your face instead of flat. PS: ignore Negative Nancy

Oh I can feel my blood sugar levels spike just looking at that photo. Why tease a diabetic like that. Outside of just stocking one type of connector and keeping the prices and inventory down, there is absolutely no reason to use PL-259/SO-239 connectors for any VHF/UHF radio when N Type connectors are better. While N Type connectors are definitely more weather resistant, I still wrap them just like I wrap PL-259 connectors out of habit.

It's always a trade off when determining what type of coax to use. For the average person setting up a base station where the coax run is 50 feet or less then LMR 400 and equivalent is fine. Just like every type of antenna is a compromise. Go with what works best for your situation and that also fits your budget. Not everyone can afford LMR 600 or 1/2" Heliax cable.

You will get a baker's dozen if you can get all the radio manufacturers to start using N Type connectors on all HVF/UHF/GMRS radios.

Two very important tips to always remember.
