Search: Windom Antenna Vs G5rv. Really impressed with this G5RV, very well built, just had to connect the 300 ohm window line to the feedpoint and seal it up then I found I could use it on most frequencies without an antenna tuner and it compared favourably to the Windom G5RV Plus™ SuperLoop™ 80: CAROLINA WINDOM® 160 Special: CAROLINA WINDOM® 80:.
I am interested in an Automatic Aerial Tuner for use with a long wire, well, part vertical actually, and I am drawn to the CG-3000. This is an auto-atu that is sold by Martin Lynch and was reviewed in November RadCom. You can purchase one from ML & Sons for £199.95. Consider then, the MFJ-926 auto-atu as sold by Waters & Stanton.

Using the multi-band doublet with a manual ATU, first is to find the correct antenna tuner settings for each band and to make a list of the settings to be used when changing bands. As I use cw, I looked at matching the antenna on the cw section of the HF bands starting with the 20 meter band. With the feeder connected between the antenna and ATU.. I figured the best way to check the performance was to start @100watts on the low bands 40 through 160. I use a IC7300 with a ProII auto tuner, It has found a flat match everywhere even at 1.900mhz. It should be said that I have an extensive ground system in place. With 100 watts 40-80mtrs I managed 20+ signal reports up and down the east coast.

Tuner Genius and a doublet antenna. Unfortunately TG has no provision for connecting a doublet antenna. Usual solution is to connect a 1:4 balun to the output of ATU. My concern is that , considering PG's high power output, it may result in excessive heat losses.

3. A single antenna that functions over such a wide band will necessarily be less than ideal. Compromises must be made to achieve such wideband performance. The antenna will have to be at least big enough for the lowest band, so anything significantly than 259 feet will be quite difficult to get working on 160 meters.

Ok. so this is my first attempt at a doublet antenna. I used 132ft of 14ga copper wire for the main antenna line, a length of 300ohm flat twin line to run down to my KX3 and auto tuner, and an extension cord winder to attach everything to and wrap up the wire for transport. I have yet to test this antenna but I hope it will perform well.

Jun 30, 2020 · It seems I can either feed the open wire directly into a remote antenna tuner that accepts balanced feedline, or terminate the open wire into a balun then run coax to a tuner indoors. It seems the coax losses would be terrible if I went with the latter. Are there any remote automatic tuners that can be fed directly with open wire?.

The all-band doublet is actually an antenna system and not just an antenna alone. Fig. 1 shows the basic elements of the system. The horizontal center-fed wire forms the antenna proper, which accounts for the radiation of transmitted energy and the reception of incoming energy. The parallel transmission line transfers the energy from the.
