Diamond Antenna BB7V

I have this mounted on a wooden deck with the bottom of the antenna about 4'AGL. I tried it with both 1/4 wave and then with random length counterpoises and compared that to just the antenna without counterpoises There was no improvement in SWR so I am using this antenna without any counterpoise or grounds and it works really well with 25' of RG-213 and no choke at the rig. It is fast and easy to deploy and take down this antenna and is very well made.

I had this on a tripod about 3 ft above the ground and it did good talking local and long distance at night. I called to ask Diamond if I put a counterpose down on the ground how much it would help.

The tech told me that this antenna was designed to work at 23 to 25 feet no counterpose needed. I changed the height and man what a difference. I actually talked on 20m from Washington to Indianapolis speedway for the Indy 500 and checked in during the middle of the day and got a 5.8 with a 100 watt Yaesu FT 450D.

So, that is the way to run it if you can. Yes I would buy another one.

Bottom of can sits 6in from ground. Ok not the best but from east coast of NC have worked from Dallas to Connecticut to Fl Keys with 57 as low, Cuba contest at a 59. Of course I'm working with a Kenwood 440s I've had for 30 years.

it's crazy but you would be better off with an antenna mounted to your car that requires different traps for each meter that you want to use. I had this antenna at 1,750 feet looking over the tops of mountains mounted 25 feet in the air and I could only hear about three people on a net that covers Oregon, Washington and California. My friend with his antenna that requires changing cans for every meter, could hear about 70 % of all the people and made contact for the net which could not hear me. We both have the same radio and he was about 7 ft above his truck and my antenna was 25 feet in the air which the antenna is made for. I am highly disappointed. Ease of use is great, tuning is excellent on all bands but if you cant hear or they cant hear you, what's the use. I am a diamond man. Three 2/440 magnet mounts on my vehicles and a HT510xd on my house, love them all, but not this one.

I have had this antenna for about 2 months. I receive signal reports of 57 thru 59+. This is a fantastic antenna for limited space, would recommend this antenna highly!

I have had this antenna for just over two weeks, I have worked Europe, South America, and most of the north east USA, I live in Georgia, and am very pleased with the performance of this antenna.
