DK7ZB 7 ele , i had the dipole V-shape but that was a big mistake the 45dgs V-dipole did ruin the performance f/b . Now original DK7ZB working good. The V radiator experiment cost me a lot DX...
Having relative poor signals on the local 70cm / 2m channels using this X50 Diamond collinear 70/2 1m antenna at a height of 25m. I needed to investigate what could be wrong. Measuring the cable only 3W is left for the antenna of the 10W 435MHz output from a IC451E The cable is 30m type H100 Z50 10mm outside diameter it is semi air-spaced but has an impossible 4mm² solid CU inner conductor not much air left. I preferred the H43 Z75 cable having lower loss and mechanical better ratio in conductor size. My antenna uses SO239 connector UHF type semi air spaced isolator. 3W should be enough for a comfortable noise free FM signal. But only 27km away at PA0A the signal is weak too weak something must be wrong? I made a simple reference dipole of 2x17cm CU wire. With this dipole the signals where totally worse. So the Diamond does work? I got curious to look inside. Maybe moisture penetration degraded the antenna. This antenna is rainwater close in its n...

heb de 5el dk7zb voor 4m die werkt goed maar op 4m is gewoon niets te werken hier
1x een dove A92GE , Kazakhstan nooit gehoord overal elders in PA werd dat gewerkt
Toen heb ik 4m geschrapt voor dit jaar
Ik las een artikel over V vormige elementen voor een 3m yagi en dat dat zo goed werkte
toen heb ik het ook geprobeerd
