Hmm, i find someone should do a real mobile (mobile-mobile, with a velocity > 0) experiment. A 1.5 m long CB antenna with a special preparated feed point should work. And i think that the wire works
have all the formulas in your mind :-) Yes Stefan, sure do... this is the kind of stuff I sometimes like to think about during my bike ride to work - about 70 minutes, twice a day ;-) Ok, no pocket
Sorry Markus, can you do all the calculations again for 475 kHz ? :-) 73, Stefan Am 28.05.2015 01:23, schrieb Markus Vester: I bet you have all the formulas in your mind :-) Yes Stefan, sure do... th
Hi Stefan ! but most likely there is a LOT of QRM when driving... It depends on the type of car. While testing /mobile on 160m I did not hear QRM from my 23 year old Diesel. At the Autobahn, far away
Ah, sorry, i didn't read your mail until the end. OK about your argumentation and of course i know that from the VLF times :-) But you need to consider the changing angle of the wire while driving. I
Hi Stefan, G3YXM was mobile on 136kHz many years ago. See http://www.wireless.org.uk/mobile.htm , scroll down to middle of page. If it is possible on 136kHz then it should be a piece of cake on 475 7

I well remember that many years ago there was a photo in either Radcom or Short Wave Magazine, of an Austin Mini equipped with a rather large base-loaded Top Band (160M) antenna with the caption " Th
Stew Perry, W1BB, or mister top band, regularly operated 160M mobile. An inverted plastic bucket covered the large loading coil needed to match the whip, which had to be limited to a maximum height o

Revisiting the topic... My ERP calculation was erroneous by a factor of ten (looks like I can no longer do without a calculator). It should be radiated power = 0.0256 * 160 = 4 microwatts or -24 dBm
