Diamond Antenna X700HNA

I had purchased one of the Diamond X 700HNA antennas back in 2019. It was what I thought was one of the best antennas until recently. After a rain storm I discovered my SWR went very high. I took it down to discover it was had water in the middle of the core elements of the antenna. I also discovered it had a winding in the middle of the antenna elements cracked in the hollow tubing of the element. All of the joints O rings where devolved and crumbling away, in other words GONE. This antenna is only 10ft. off the ground attached to the back of my house. For a $450 dollar antenna it should last much longer than 3 1/2 years from installing.... I would not recommend it unless you want to replace it evey 3 years.. Good luck... KG5WRS

I use this for a lot of simplex action here in PHX and this antenna works very well. I am picking up stations farther than I thought possible from my home station. I worked an HT on a mountain top 130 miles away. PHX to Flagstaff. Very impressive.

This Antenna is Great on vhf and uhf. Using it on a vhf repeater 100 watts..Excellent coverage.
Use Uhf for 70 cm control radio and Irlp. All togather. I recommend this Antenna.

Worked great at 70 feet but it did not like the ICE lasted less than a year.

IMO the BEST 2m/70cm vertical on the market. Well engineered and manufactured. Great signal reports and excellent reception. Save up your money and get this one!
