I've recently installed my new Optibeam 11-5 which has turned out to be an awesome antenna. Being disabled means I have to rely on other people to do my antenna installation for me, I'm just a bystander that can really only offer a little bit of advice and guidance. Now the Optibeam 11-5 at first glance when taken out of the box may look rather daunting when it comes to assembly and installation. However, I can tell you straight away that this antenna is an absolute piece of cake to put together, as long as you read the instructions properly. I cannot emphasise enough how important it is that you sit down first and read every bit of the assembly installations before even attempting to put the antenna together. The antenna has been cleverly designed so that you simply bolted altogether, there is no need for tuning or any complicated measurements, just follow the instructions very carefully and you will not have any problems whatsoever, I can almost guarantee it. The people who do run into problems are normally people who can't be bothered to read the instructions properly.
During the installation and assembly of the antenna, we did have a few minor problems, most of them turned out to be a case of not reading the instructions properly.. We also had an issue with a small component that got broken. However, Tom, DF2BO the COE of Opti beam was extremely patient and helped us with every single question I had. When the small insulator from one of the elements got broken, he even sent me a brand-new part completely free of charge. I really can't thank Tom enough for all the support he gave me over the few weeks that it took us to completely install the antenna. Even on a Sunday afternoon he was there answering e-mails within an hour or two, the support this company gives its customers is second to none.
As for the antenna, I am absolutely delighted with it, it is an absolutely wonderful piece of German engineering that has quite obviously been designed with a lot of thought in mind.
If you are looking for an HF beam them look no further than Optibeam, they really are at the very top of their game when it comes to design and performance in HF antennas.
