After finding out that a commercial one was around £50 I decided to make one. Strip away the outer cable, the braid, and then the foil covering the center conductor. On 160m a Lambda/4 radiation is almost 40m tall. There are current and heating considerations that have to be allowed for with a vacuum cap - especially when partly meshed. the loaded vertical (see below); 2. Actually, JF1DMQ wrote an earlier article about the Flag antenna in November 1995 in a Japanese magazine. , sunspot numbers. It took several attempts including a top loaded vertical of 28 mh with 20 ground radials each 40m long and laid within the property limits. Moreover, the width and location of the slots can also adjust the rejection bands. Typical SWR readings in most bands and installation permit a tuner free operation on all resonant bands from 160m/80m/40m (non harmonics related bands like 60m can be used with the help of an antenna tuner). One interesting thing I found was that when tuned to the 160m FT8 frequency, it actually tuned up pretty well on 6m!. Although designed with the new Icom IC-705 and other QRP transceivers in mind, the CHA MPAS Lite can handle up to 100 watts in SSB or 50 watts in CW. The single Rohn 25 vertical we had been using until now was an excellent performer, but it was time for something with more. You can transform your existing tower into a high-performing DX 80- and 160-meter vertical antenna that operates at the full legal-limit power. Until about three years ago, I could only dream of being active on that band. On the receive side, the standard 160 meter antenna is a Beverage of some form. So, you can't "cheat" at 160m, you will most likely need the full loop for its lower band edge frequency. The HybridDX™ has been tested on 160m with both modern and vintage tuners, including the MFJ-993B IntelliTuner™, SGC SG-239 Smartuner™, Palstar AT2K 2000 HF antenna tuner, MFJ-941E Versa Tuner II, MFJ-969 Deluxe Versa Tuner II, and Ten-Tec 228 and 229 tuners. antenna and explain some of its characteristics and its best characteristics. to gel on 160m. 0 ms, thus the fre-quency of rotation is 2 ms or 500 Hz. Most of them, however, performed substantially worse than the reference antenna on the lower bands (i. My best DX on 80 with the inverted L was the East coast from Oregon (pretty easy on winter nights) and Hawaii on a 160 meter version. Yesterday, I worked VE1ZZ on 160m CW this morning around 6am. I’m open to learn from your experience. Construction method is as usual with me, a bit sloppy for the time being. Windom's original idea was off-center feeding a horizontal antenna to present a feedpoint impedance of 600 ohms. On RX the normal noise level on the antenna at around 18:00 is 2-3 S units and dropping to zero in the middle of the night. This is the ultra rare Murch Model UT-2000B - this antenna tuner covers 1. The antenna described here is small enough to fit into a corner of almost any backyard. 30 KHz tuning ranges for 160m, ~ 1800 - 1835 and 1830 - 1865 MHz, or are available using a front panel range switch. Noise Canceller: Every 160 meter enthusiast should consider adding a noise canceller to their list of ham radio equipment. Over on our store we've recently released our new receive only dipole antenna kit which now replaces the older magnetic whip style antennas from the previous kit. Runs from maple tree thru flag pole to 35 ft telescoping fiberglass mast to bird house pole. To construct the 160m loop you'll need 20ft on RG-59.
