Jim, Perhaps I miss-understand your question, but the 9 circle array designed by W1FV is a multiband array and is effective on 160, 80 and 40m 73, de steve ve6wz _____________________________________
Stan, FB on ordering and sharing your boards. Most manufacturers have a minimum order. Mine from JLCB cost $30 for 5 boards delivered to the door in 5 days. Indeed it seems to make sense for guys to
Why the F wont it go on ? I have probably installed over 150 F connectors to RG-6 in the field for my Beverages and other RX antennas. Im sure many on this list have done the same, but tonight I uplo
Here is an update on my new 9 circle combiner board, and some comments about performance, and the array in general. First, I have already made a revision to the PCB. The latest is Ver. 3.2. However,
Dick, I have a total of 25 Beverage wires in the field currently. I used to use the Ohmite ceramics, but now all termination resistors have a Gas Discharge tube across them. Now, almost any decent re
Hi Dick, As others have said, also add a GDT across the Beverage feed box, between antenna and gnd. Adding another across the coax at the feed box is good prevention too. This will prevent vaporizing
Hi Gary, The data sheets for these GDTs provide some info about expected life. For example, the light duty GDTs that I gave the link for says that they are designed for 300 impulse operations at 100A
Put a proper compression F connector on the RG-6, and use an F to UHF adapter. Type: f type to UHF and search Amazon. Lots of hits. UHF is 50 Ohm. F is for 75 Ohm. You wont find a direct UHF connecto
Indeed SWR is not a measure of Yagi antenna performance. However Yagi performance IS a function of the narrow bandwidth of a shortened PARASITIC element. (not the driver) Explained here regarding a 2
Today I uploaded a short 6 minute video showing how to use the Kiwi radios located all over the world to test your transmit antenna. How is the front-to-back on your 4 square really performing? Make
