Hi Kenny, I added a second wire to my Tee many years ago; at first the vertical section was about 80 ft, now it's closer to 100 ft. My spacers are sort of random, on the order of 8-12 inches. It did, indeed, increase the SWR bandwidth. I'm using a lot of on-ground radials of varying lengths. 73, Jim K9YC _ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector
Re: Topband: W6 to EU openings last night
guys, Conditions to EU have been excellent this past week from Arizona. Looks like the sunrise enhancement has finally returned. I have never seen EU with S9 plus 20 to 25 at this location in the past 30 years. Let's hope for similar conditions for the commons contest. n7dd Sent by Larry On Jan 5, 2021, at 10:32 AM, Michael Tope wrote: I tried calling CQ on CW at around midnight local (0800z) this morning and worked JE1CTM, G3PQA, G3OQT, and G3OLB in succession all with good signals into Southern California.

Topband: Shunt fed tower - wire cage
I have an 80' Rohn 45 tower that I shunt feed. At 85' there is a SteppIR MonstIR. I set it on 7020 when I want to transit on 160M. The setting of the antenna has a dramatic effect on 160M with SWR. I have side mounted antennas at 45' and 50'. The shunt feed is a set of three parallel #16 enameled wires 18" from the tower face. The shunt runs from 6.5' above ground to 40'. I use a pair of vacuum variable caps as a gamma match to tune the shunt. I also have a third vacuum variable cap and a vacuum relay to switch from low and high 160M. My question - any reason to use a larger gauge wire than #16 for the shunt such as #14 or #12. Would it make a measurable difference?

Topband: Band Conditions
Well Conditions were good last week . . . On one evening I worked about 30 North American stations on CW, including across to Texas, Colorado, etc. Rick I was on last night around 0100Z and again about 0300Z. I did work Dave VE6WZ in Alberta, however, I could see from NA RBN Reports that propagation was poor . . . however a station in Oregon logged me at 45 dB above the noise a couple of times ! If I wake during the night I try and come on around the top of the hour, and put out a few CQ DX calls . . . but if propagation seems poor I go back to bed after ten minutes ! 73 Roger G3YRO _ Searchable Archives: http://www.contesting.com/_topband - Topband Reflector

Re: Topband: Cage wire performance
Kenny, For the Baker Island KH1/KH7Z DXpedition I developed a 43 foot "T" antenna with spreader wires (Fat Vertical) with sloping top loading wires. It performed very well. I have been using a 65' version at C6AGU for the past two years and it has been performing very well. (There is a picture of it on the C6AGU QRZ.com page.) NEC modelling indicates higher gain (6 dBi) and wider bandwidth, BUT making the antenna "fat" lowers its radiation resistance, which places greater demands on the ground system. (Both on Baker and C6AGU the antenna was standing in salt-water.) The C6AGU antenna feed-point impedance was measured at 9 - 130j Ohms. (I use a remote tuner.) If you measure a much higher resistive component, it could indicated that you need to improve the GND system.

To improve the bandwidth, I was wondering about going to a 2-wire “cage” for the vertical section. I’m actually modeling a skinny triangle where the wires connect at a point on the top, but with a 4 foot spread of the wires near the ground. This adds about 15-20 kc to the 2:1 bandwidth per the model. Will a 2-wire section like this always behave as a wide/fat conductor or do I have to worry about voltage/current in Each wire?

Re: Topband: KD9SV hardware loss reverse direction
Hello Andree, The loss you observe primarily depends on a loss in WD-1 wire used as in a transmition line mode. As wire made by different manufactures, with different polyethylene, steel and copper strands, and tolerances in size its impedance is different. And of course mismatch in transformers occurs increasing the “loss” you observe. From our experience at LowBandSystems we believe 150-200 meters is a practical limit for this type of wire to be used in a transmition line mode. But it should be checked. Anyhow WD-1 is a cheap and good solution for those with limited property not allowing to install a long beverages.
