At that height - I would suggest a vertical antenna, and use the 432 stack as a capacitance hat...would work much better, with lower angle of radiation (good for DX) than a dipole. My 0.02 worth... S
I have had good luck with Lowes and Home Depot - both of which stock a good supply of metric bolts and fasteners. Scott KB0FHP Hey all! I recently aquired an used beam antenna. Planning on replacing
I have purchased several sections of Rohn 25G - 3 straight sections, and the 8' top section with rotor plate. I want to attach this to the side of my two-story house, at two locations (top header boa
Thank you Bill...Actually I can't type. It was 2 sections and the top section - for 3 sections total. I was planning to put the TH3 on the bottom of the mast, then put the 6M beam, followed by the 2M
just business....just business... Unfortunately, it is not just domain names that get hijacked ... There is one amateur radio manufacturer in Italy that hijacks his competitor's names in the search e
I am looking for plans for a transformer/balun to couple 50 ohm at 50Mhz to 300 ohm. The purpose is to load a TV antenna, allowable by HOA, on 6M. I have tested this antenna, using the standard trans
I was looking for a narrow band solution, and repeat it using different dimensions for 6M, 2M and 432...But I like the taper feedline solution - very nice. Over what length must it taper? Scott How w

Does anyone have a manual for the older KLM 14 element 2M beams? This is the one with the 4 driven elements. It is not the circular polarized elements. Thank you Scott, KBØFHP ________________
Personally, the use of quench oils used in heat treating also works well. It is typically a high grade paraffinic mineral oil, with oxidation additives added for this severe duty. These can be obtain
Anything less than a stacked 40M array at 160 plus feet will just cause unnecessary QRM for the REAL MEN and the DESERVING..... (Just kidding)... I can help you model it, and provide you with some gr
Try MMANA - applicable to more antennas than simply Yagis. It also has an optimizer. I have used this program many times, and the results compare very well with results from YO, ELNEC and other model
anodizing is probably the best thing to do. Alodining is also effective, and there are several types of brush on alodines. You can get pretty colors too - for instance the bright blue of TV antennas

My experience has been similar - it doesn't work well on 10M and 80M - but I did work DX with it - mostly Europeans. I found that on 40M it works excellent - this was also borne out in independent te
Pinning coax is so old school - now they simply kill your dog, firebomb your house or fire assault weapons at your family. Much more effective..... Having heard of people having their feedlines "pinn
Shorted to the mains leading to house I have a question: BTW I agree not to work on antennas in a thunder storm. Had lightening hit (not sure what it hit) about twenty years ago and the walls in the
Depending on the specification: Condition N is normalized and ready to be heat treated. CDSR is stress-relieved. More than likely the material is in a form similar to hot rolled, and not normalized f
Trouble with aluminum, is that it oxidizes, and causes an oxide buildup at the connection. This increases the resistance. At least for home electrical wiring, special connections have to be made. But
There are really two questions there combined into one question. Schedule 80 is a pipe wall thickness designation....It does not specify alloy - there are approximately 30+ alloy designations for pip
