What kind of SWR is being experienced at 20 meters?

My FT-450D won't tune this antenna at 20 mtrs with it's auto tuner. I can use my MFJ 949E tuner to do it, but I use a wire on 20 mtr and longer bands.

Depends on where you tune the antenna. It's broad-banded, 27-28 Mhz 5/8th wave, which is physically 1/2 wave at 21-22.5 Mhz. Try twisting the tuning rings nearly all the way to the top. It should center tune around 28 Mhz and tune 1.5 swr up to 29 Mhz. Additionally, it should tune great near the middle or top of 20 meters (21-21.450 Mhz.) I installed the stock ground plane accessory and also cut four additional wire ground plane elements @ 1/4 wave of 21 Mhz (approx. 11 feet) Works great. However, you may not need the ground plane if you are less than 30 feet above ground.

I have a chart of my measurements on 7/16/13. 20m shows SWR @12, 17m @ 6.6 and tunable with my FT-450D on 15m, 12m and 10m to about 28.825. I use a MFJ-902B Tuner to pull in the 17m, 20m and 40m bands. From my RV in Minnesota this summer I worked HI, AK, FL, NH, ME, NY, Chech Republic, Canada and many more. You of course lose some output by using the tuner but that does not seem to make much difference when the bands are open. I admit it is a compromise but it certainly fit my need of easy breakdown and setup. My home QTH is in Florida and there I primarily use a horizontal wire and now use the Solarcon for 10m. You can check out my logbook using my call KK4itx on QRZ.com. email me at my call @arrl.net and I can forward my measurements of the antenna. 73, John

YesBelow 20" it reads to 0.00"But I'd say if you are using it for that low of a range I wouldn't use this one

I started at 20 yards. You need to find your comfort range and start from there. Once you lock in your stating range the rest galas into place with practice.

I've gone as far as 20ft, but some of my friends say they have gone even further. I use mine with my cell phone, so there's really no need for me to go far.

I used it for 20 meters and it has worked perfect, that if no physical jimmy

i have never tried it from over 20 ft i record a lot of things off utube and it is very clear and thats across the room from what i am recording. i am going to try it sunday for the services and that will be 40 ft or so and i can let you know if you like hope that helps

I just perchased the H20. I'm use to having a view finder. I thought there may be a way to rig some kind of sighting device. The camera already has a means of sighting in. Looking from the rear of the camera, there is an elbow formed to the left side of the flash "hump". If you bracket your subject in this elbow it'll pretty much end up dead center of your shot. Hey, it's not hi-tech but the method works.

You can see 20-30 ft. with pretty good accuracy. Remember the further you are away from the target the less accurate your readings. If you leave the camera on MSX it will enhance the image. Darryl Mendivil

Fps is feet per second and 20g bbs is the size of your bbs. I've also used 6mm bbs.

It will get you within about 20 feet at best. Better mark the spot with something discrete.

In suburban conditions, GMRS (if you are licensed on this frequency) could give you 1.5 miles (as the crow flies), but it's really stretching it. FRS will give you 500 yards, plus or minus. Out on rolling range, I have done better, but when you are out of the line of sight, it's not good no matter the conditions. I have used both Motorola and Midland and Midland has superior propagation, but these types of radios are by their nature a half step above a toy. If you want additional range, get an amateur license and operate on the 2 meter band, but that is a process and the equipment cost is is not $60 set for a set.

20-25 ft. distance is what I have been able to get. Beyond that is very iffy.

flat out we havent a clue how accurate the number is. but the one I bought is consistant. the calibration knob is used to get your SWR its not used to calibrate the meter

The spec says 30 ft, but I've experienced a range of somewhere between 20-30 ft

I've got about 20mils of usable elevation mounted on a 20moa base,but the total range of adjustment is 30mils for windage and elevation.

I bought this camera based on the 75-100 ft responses here, but I'm very disappointed in that mine will only trigger by a human at about 20 to 25 ft. I can start walking slowly towards it from 150 ft away and the only time it takes a photo is when I'm almost on top of it. Very disappointed!

Receiving a signal will neither the need to measure "swr's" or power since all the activity on your antenna is incoming. Here is a good article from "Radio Reference" about random length long wire antennas. This site is a great reference for anything radio. Good luck and happy listening. http://forums.radioreference.com/hf-mw-lw-general-discussion/176209-longwire-shortwave-antenna-help.html
