FICTION! I acquired a COMCRAPtenna in an estate sale lot. It appeared to be unused, but with no paperwork. There are no markings on the antenna anywhere, apart from the stick on label that only says COMCRAPtenna. An email to COMCRAPtenna, asking for info to assist in identifying this antenna model n number, resulted in a reply from Jack Nilsson. Asking questions such as, "where did I buy it?" What does the spec sheet say?" I got nowhere with this guy. Jack Nilsson <email@example.com> Hi Marc, What was it when you bought it? Jack Nilsson <firstname.lastname@example.org> About how tall is it? All this and then proceeds to tell me I didn't check the VSWR, which would prove nothing. Then, somehow this light bulb goes off in his head... ? We concluded that since you didn’t mention the permanent ink ‘D’ for dual band (2M/440) or ‘T’ for tri-band (2M/220/440) on the bottom recess of the antenna, that it had been removed between who had the antenna that you describe as a dead person and you. It was also logical to conclude that you didn’t check the antenna for SWR (which also identifies frequency/bands) per the instructions that come with the spec sheet and on the website before operation. Well you explained getting an antenna without purchase from someone who is deceased. We hope you have enriching experiences with COMPACtenna technology. Have a great day and a good year! Why have me jump through hoops if the antenna was supposed to be marked? This guy is full of it and so is the antenna. I swept it 100 MHz to 600 MHz on an Anritsu SM, which alludes that his antenna may be the tri-band model. Unfortunately, the VSWR bandwith is too narrow. The acceptable VSWR, is outside the 1.25 and 70cm bands. I may cut the thing open and post the pics. It's just a can of snake oil anyway. No enrichment from COMCRAPtenna here! I'll stick with my quarter wave antennas thank you.
