News Flash,

Station KC4ZGP is now on the air, 10.109MHz, Morse code.

Magnetic loop:

standard measurement, 50 watts, 5 feet by 5 feet square, gamma matched, stands near ten feet at the top.

metric measurement, 50 watts, 1.5 metres by 1.5 metres square, gamma matched, stands near 3 metres at the top.

Mike/VE3YF,

When all start making sense all the time, that's when we hang it up and go home.

Does that make sense?

80m dipole up 75 feet (23m) and fed with ladder line/tuner. Works FB on 30m.

Yes the 2x21m doublet or thereabouts works FB on 30m with considerable gain! I had that at old QTH and it had gain toward NW (EU short path), N (JA), NE (USA short path) all at the same time, due to sloping down to the North. A great antenna. My current 30m ant is more modest 2x6m (+2x1.4m) up 9m and favors NW/SE. Details at http://30cw.net/vk5eee

6BTV here too. Works great on 30.

Now I need to put something up for 17M....

Transworld vertical dipole from DX Engineering. The 30 box works really well, much better than I ever expected.

6BTV here as well.  Also works well on 17M with the DXE add-on kit.

At home, I mainly use my low stealthy wire with a 9:1 unun. In the fields, it's either a mag loop or an EFHW.

Hi

I only have 2 antennas right now.
A trapped 80/40M dipole inverted-V with feedpoint at 35 feet.
A ladderline fed 2 x 23 feet V-dipole, wich I use for 10-40 mtrs feedpoint at 35 feet and the ends at 40+ feet.
So were all aboard, only 160 not possible due to very small lot here.
I only sometimes listen to 30M though I realy like 30 mtrs.

Thanks all, interesting survey! PA1ZP please elaborate V dipole because of slight dip in middle or horizontally it is a V? Mine is about same size 2x6m with extra 1.4m vertically down at the ends due to space but tunes and works fine 10-40m, tunes on 80m receives excellent (no noise!) but too little power gets radiated on 80m with that short length. Plan to experiment with EFHW and GP on 30m too.

I'm using a homebrew half-wave dipole made out of #14 copper house wire.  I had to take it down and clip it several times before it stopped stretching.  It's been up about three years and has held its resonant frequency for the last 18 months or so, with an SWR around 1.25:1.  It's about 45 feet high and suspended between two towers.  No balun but it has a gas-discharge lightning arrestor in line.  It's fed with 50 feet of RG-59C/U coax, which is spliced via a barrel connector at ground level to an RG-213 line that goes to a remote antenna switch nearby.  The final connection is RG-213 from the switch to the radio shack.  About 250 feet of coax in all.

The dipole is oriented with its ends pointed east/west.  I've worked 168 entities with it, and have 30m DXCC and 161 confirmed.  Over the past few years this antenna has given me a new respect for wire antennas in general and for dipoles in particular.

Good luck with that. Last week all week CQ CQ CQ Morse. Two QSO's both on Saturday. I think I have a whole
ten SSB QSO on seventeen and that's since about January.

A scant band it is I tell ya.

Dipole at 50 feet, and a R7 vertical antenna. Both are comparable.  Oddly, my 160 meter inverted L is a real bear for receiving on 30 meters!  SWR is too high for transmitting, however.
