75M Top Hatted Vertical

Simple 75M top hatted vertical I’m selling my 60′ 80M vertical with home brewed matching and switch circuit – and low band receive system. They will all be gone this Saturday. My 160M vertical is gone – and will be used by three fellows who are chasing DXCC on 80 and 160M. I’m done with that for good. However, I still want to check…

What’s He Building in There?

From the Tom Waits MTV Video of the title name When I first moved to Orinda, I put down some radials, stapled to the grass, and put up a vertical. My next door neighbor came up to the fence (we have practically wooded lots) and asked if I was with the CIA. Another neighbor came from across the creek to mention he heard some Morse Code…

60′ 80M Vertical Matching Box Built

That was fun and much simpler than trying to create a multiband matching circuit. I ended up using refrigerator tubing for the coil. It’s about 4″ in diameter, and 9 turns. The direct line was good for 3.857.5, and the coil let’s me go down to 3.515. I also have a 1:1 current choke at the input, which means the common mode current will…

80M Switched Linear Loaded Vertical

My 60′ (18M) wire vertical for 80M covers about 30 khz at the same SWR. This means I will be good to go in the CW portion of the band (center the “long line” for 3.515), and then cover where the nightly net is (center on the “short line”). 246 divided by the Frequency in MHz = Length in feet 246 / 3.515 =…

70′ Ladder Line Vertical for 80M

Using ladder line – I can use one side for the 80M CW band (70 – ish feet) and one side for the 75M side (63-ish feet). I have an extensive radial field that proved itself on 160M – earning me DXCC on that band – so now I will come up with something on 80M that avoids any kind of loading – so…

Mad Antenna Science Weekend!

Now that all the hardware (structures and wiring) is in, I can take some time to do some tests and experiments. Here is a list of things I will try with the two 60′ (18M) Spiderbeam Fiberglass based wire verticals: Tune the verticals for the DX Engineering phasing solution. Check to see if the radial field – as strange as it is works. Try…

Confessions of a “Fair Weather Top Bander” . . .

All of a sudden I’m loving 80M – and this I never would have expected Because making DXCC on 160M (without using remotes) from the West Coast is so hard, I fancied myself as a real DX “Scrapper” being able to do so. For sure, its a great accomplishment – and one that DXers on the East Coast (or those on the West Coast…

A “Hive” of 80M Activity and 3C0W on 30M

The Spiderbeam 80M vertical with wire taped to the top. Look carefully at the tall tree and you can see it I was able to get one 60′ (18M) fiberglass pole up today. The second one is going on another post – but I had to remove a bird house that the hornets took over. I took a hammer knocked the birdhouse down into…

Farewell, Top Band . . .

I’ve made my goal with 160M DXCC – which also means 9BDXCC, and because I have very limited space for antennas, I will be replacing my Inverted L with a pair of 60′ verticals phased with a DX Engineering DV-80-P within this next week. There is far more interesting activity on 80M than 160M here, but it was a great journey, and for the West…

80M: My Log Says “Variety”

I have 172 entities on 80M, and the variety is really excellent. I was listening to 160M just a minute ago and it was soooo boring. I switched to 80M and I’m hearing 3C3W pounding in. That led me to look at my log and here I am. I think the deal with post DXCC DX-ing is variety. 80M is still a band that…
