antenna or simply an antenna you take with you for a field operation or when camping. • Please be aware, the NVIS is not a DX antenna!!! This antenna system was developed for reliable communication (within 400 miles) with 100 Watts or less power. Tuning the antenna is straightforward: you cut a piece of wire (a bit long) for a 20m quarter-wave, and lay out four 10' radials. Then, you bit-by-bit trim down the vertical element to resonate at the desired point in the 20m band. Then you switch in the 30m coil and compress/expand its turns without changing the antenna length to. I've built one for 40M and it worked well on 40M and higher. Depending on your tuner, it may also be usable on the next lower band. L. B. Cebik W4RNL (SK) popularized the 44-foot doublet for 40M-10M. According to Cebik's analysis, this length produces a more consistent radiation pattern across the bands. Doublet diagram.

Everything I've read (and my understanding) seems to suggest I could get away without an antenna tuner if I tune the dipole to 20m, but everyone suggests to have one anyway. ... If you've ever tried using a 40m dipole on 20m or an 80m dipole on 40m you will know how bad it.

So I put up a separate 20M EFHW (33'-3" long) for testing on that band. I found that putting 220pf in parallel with the input (TX side) brought my 20M SWR down to 1.6. With the same capacitor still installed, I got a 1.3 SWR on 40M using the 40M EFHW. So now I'm happy with it as a "no-tune" matcher for 40M and 20M and I'm sure 30M would be OK.

After I figured out how to make my Hamstick dipole somewhat resonant on the 40m JS8 frequency, I was able to make some contacts this evening, whereas I previously couldn't even receive many stations. I'd been tuning with the internal antenna tuner but it wasn't really helping - just prevented me from blowing up my radio. This antenna is basically two 5/8 wave antennas end to end. It can be fed with ladder line from the center insulator to tuner or it can use an impedance transforming length of ladder line to take the impedance to 50 ohms and fed from there to the rig with 50 ohm coax. That would limit it use (without a tuner) to a single band – 40 meters.

In practice, it may be easier to start with an antenna length that isn’t resonant: the exact length makes little difference when a tuner is used. My experience using a 40m doublet on 40m, 20m, and 15m, is that sometimes, depending on the line length, I couldn’t get a good match on 20m with any of my tuners, but other times I could (when I. 40M 20M 17M 15M 12M and 10M - No Tuner Needed The CHA LEFS is a six-band, no-tuner, High Frequency (HF) antenna for use on the 40, 20, 17, 15, 12, and 10 meter Amateur Radio Service (ham) bands.

This antenna is a full wavelength single-delta-loop, with the point of the triangle at the top of the single support pole, and fed near one of the corners - One Quarter Wavelength down the diagonal leg. Feeding and matching is simple; it's fed with a quarter-wavelength of RG-11 or RG-59 (75 Ohm) coax, and then any length of 50 Ohm coax. vite deploy. This antenna generally requires the use of a suitable matching network (antenna tuner) since the SWR of the G5RV JR is almost certainly not 1:1 on any band.

Pin 1 is the KEY pin, when the 'TUNE' button is pressed, it's pulled low by the tuner to tell the radio to start transmitting. Pin 2 is the START pin to/from the microprocessor. Under normal circumstances the START pin is pulled high (to +12v via a 47k resistor) when a remote tuner is attached to tell the radio that the tuner is present.
