HB9-70 2 Element HB9CV 70cm Beam Antenna

As you can see in the photo provided, the antenna received is not what is shown in the advert photo.No build instructions provided also, and it caused damages in building for me as seen in the photo. Photo shows I must of damaged the capacitor a few times in investigations, I felt there was a short of some kind, not knowing the capacitor was variable was the short, searching caused Moe damages untill I noticed the capacitor dints.Due to no instructions I was obviously not made aware the capacitor was variable or warned of the design nature of the capacitor and it's flimsy materials making it prone to very easy damage, I have never seen a capacitor like this before I thought by looking at it it looked solid state and just extremely strong, I wondered what the screw like part was, I thought it was a solder mounting point at 1st.The antenna came ready built, but it took me over 1hour to figure out why the antenna tested working as expected with a VNA after soldering, upon closing the connections compartment lid and did a final before use VNA test, tested a fault of high swrRecently I bought the same antenna in 2meter version from moonraker and resorted to using that manual, the 2meter version came with a coax cable stub for the capacitor, unlike this 70cm with no instructions.Even on the 2meter version there is no inner coax cable mounting point.I would not trust these antennas outdoors in winds unless you are prepared to I assume risk voiding your return rights and make modifications like glue the cable or drill holes and cable tie the cable in place, i'm not sure how moonraker would feel about modifications like this in the event of a early days return or replacement request.I have made no modifications, and requested a replacement variable capacitor and instructionsEdit:-Fixed it in 5minutes ... I just removed the damaged variable capacitor and replaced it with a coax stub that fits nice in the container, and I got a 1.25 to 1.35 swr right across the specified 430-440MHz, I trimmed the stub as watching on the VNA and the stub ended up around 5-6cm long that fits nicely in the container.I think the problem is due to flimsy material of the supplied capacitor that was colliding with what appears to be to raised screw holes when closing the connection container that caused the damage.

The connection method is fragile and there were no instructions, the connections were also loose and must be checked. otherwise it works OK.
