FM is constantly upright as well as weak signal SSB is commonly horizontal although some times upright. One pointing up for an upright radiating component, 2 straight BNC’s to create a dipole and one aiming down for the coax feedline. In this electronic era, individuals always watch out for simpler options. So acquiring any products like 160 meter antenna is only an issue of time for online shopping. You can quickly acquire products anywhere and anytime and cancel them too.
I stayed with the 50-foot length because I wanted to use the whole pool of speaker cable for these projects. Of course, you’ll require an antenna coupler to match these cords to your rig. The SOTA Tuner I utilized worked fine, yet each cord operated only on a solitary band. I cheated a bit and utilized a few other scrap cord to make two short counterpoise wires, 5 feet for 40M and 3 feet for 20M.
I added a spade lug on one end of each cord and made a little loophole in the other end. Obtain a 50-foot size of two-conductor audio speaker wire. In a previous message, I discussed an antenna of mine that went missing out on. The antenna in question was a variant of my old Buck Store Unique. After I built a replacement, I located the original in my truck. No worry; as the name recommends, it had not been a substantial monetary investment.
There are definitely better methods to build a delta loophole. However, I just wished to see if I can build a functional antenna making use of only inexpensive audio speaker cable. You can, nevertheless, cut the leftover cable in fifty percent to make two radials for 20M. I mounted a spade lug on each of these wires and twisted the other ends to make a little loophole.
The feed factor of the antenna is about 3 feet off the ground. Now you have cables that are roughly a halfwave on 40M as well as 20M. Cut a solitary piece of cord about 5% longer than your antenna. Do not utilize twin lead for this cable; use a solitary uninsulated cable.
Throughout my first outing with the half-square, I was able to make contacts on 40M, 20M, and 15M at 5 watts without problem. The antenna is a half-wavelength on 40M, and it appears to play well on that particular band. I had numerousReverse Beacon Networkspots on 40M showing a signal-to-noise of 20db or better. I applied some Goop ® adhesive to the loophole at the end of the wire to hold it together. I additionally added Goop ® to each of the various other add-on loopholes.

Furthermore, after the pandemic, increasingly more people tend towards online purchasing. I utilized a ring incurable to end the 50-foot cord. Keep in mind that the terminal is kinky over the cable’s insulation. The metal ring terminal is electrically-isolated from the antenna wire.
Like my otherspeaker cable projects, this antenna is constructed from a 50-foot size of cheap, two-conductor cord. mobile CB radio antenna These outcomes, obviously, are very dependent on the tuner you’re using. There’s nothing special about the 50-ft size. You can cut the radiator back to a size that offers an easier match.
It’s all developed; I just need to get out someplace to establish it up and see how it functions. I watched Mike K8MRD reveal the EFHW cut for 20M then added even more cord utilizing the banana plugs to make a resonant 40, 20, 15 and also 10M EF antenna. A high effectiveness system that can be used as a sloper or with a pole as an inverted vee! The adaptability of these antennas is mind boggling to me and also I am starting to explore various arrangements. Strip off around 1/2-inch of insulation from one end of the 23-foot cable.
