Do they have a 50 Ohm resistor built in to load them ? How does it perform given it is mainly loading coil and not much element ?
The season of Spring: a new Stargun thread to get thru the rainy days.
Well if someone would stop resurrecting long dead threads we would not have yet another Star Gun thread . https://www.worldwidedx.com/threads/perfect-example.89265/page-2#post-760275
The ongoing dilemma of
1). Not having the budget for a lay-down screwdriver to affix to the aluminum roof of my travel trailer; and,
2). An alternative to be able to quickly (relatively) assemble and disassemble a portable antenna where the ground space is restricted and space to store said antenna is primary;
3). Leads me on all sorts of goose chases. Aside from the manufacturer website one is hard-pressed to find good reviews of an Isotron.
— Twenty years of the Internet (and a longer span driving trucks on-off) I’ve not ever seen one or heard of one in use.
Not to say it hasn’t happened. Bad as are composite-body tractors word would get around fairly fast even if only in one region.
I’ve thrown money around re radio in excess of my relative ability. Made this a priority. Not sorry to have done so, but it has hurt in other ways.
“Maybe” it’s an O-K receive antenna (maybe). But there’s not enough information otherwise to make this an encouraging venture even for someone willing to experiment, IMO.
I wonder if this alien antenna would out talk aSeen this truck twice already. I parked next to it the other night and got some some pics to share here to see what you guys think!
Maybe this guy is on this forum since he's a radio guy and can give us more insight to his antenna.
This truck has another set of this same antenna on the other side so I assume it's a co- phased setup.
What I see is 2 equal length horizontal elements with loading coils with cap hats on each element. There is also a shortened vertical element with the same length cap hat on it. The ground radials at the end which are far to short to be really effective but at least they are mounted to a non-conductive mast and not on the hot side of the antenna like many of those so-called cheap ground plane radial kits. The antenna does has some serious looking mounting brackets which is good due to the weight and wind loading.
From what I see, this wouldn't be a very good local or running down the highway antenna due to the horizontal elements. Typically mobile antennas are vertical so this is the wrong polarization to be effective against other mobile antennas. But, that antennas vertical element may skew the signal in an angled V pattern creating some kind of dual polarization.
The 2 elements close together and being equal length don't seem to be effective at creating a "beam antenna" not to mention what the same antenna on the other side is going to effect one to the other.
However, this is one of the more fascinating mobile antennas I have seen in recent years!
