I've been using an end fed half wave vertical for several years with my K1 for portable ops.
EFHW's are very popular with the Summits On The Air crowd, and there are several varieties of transformers that will get the impedance down to what the ATU in a QRP rig can handle. Some have added links for band change, KT5X has a trapped EFHW.
The other thing I have encountered with verticals vs horizontal antennas in an urban environment is that verticals are inherently noisier.
True ... not always, but as a rule of thumb from many years ago, a vertical will likely be noisier. I have a GAP Titan up on the roof that I use for the top two WARC bands mostly. My other two wires will radiate but because the antennas are large compared to the wavelength, they tend to squirt my RF in all sorts of useless directions. There are times, however, that the vertical is as quiet as the tribander on 20m.
I'm always amazed at how well my magnetic loop works when in the field. 73, Fred K6DGW - Northern California Contest Club - CU in the 2014 Cal QSO Party 4-5 Oct 2014 - www.cqp.org ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
