J Pole / portable antenna?

[Littlears]

Hey folks

any idea where I can get a good quality J Pole / portable antenna which works on 462/467 MHz as well as 118-174 MHz & 375- 550 mhz ( essentially gmrs and uhf/vhf)?

If I’m really going to be picky preferably swr below 1.5 and some be gain would be nice

ive got a icom 2730a and midland mxt115 in a portable base station.

or maybe 2 different antennas for the different frequencies?

much appreciated.

You can easily get those that work 2m/70cm.
I don't think they will have the SWR band width to work up to 550.
You may have to use a second one.
Someone else may know more about it...

This one breaks down. It does as well as any jpole. I have one.

Hey thanks. That link doesn’t seem to work. Mind sending me the details?

If you have some 450 ohm ladder line why not make extended double zepp? I have talked from h t hilltop to a mobile 170ish miles.

i would but I don’t have any of the supplies.

Info to make EDZ here:
http://webclass.org/k5ijb/antennas/Extended-Double-Zepp-W4RNL.htm

When I made either of my EDZ antennas I used two pieces of wire, each one the combined length of the radiator and twinlead. I fastened my twinlead to nonconducting material at the proper spacing for 450 Ohms, and then ran the radiator wires at right angles to the twinlead. One wire for each side of edz.

Ed Fong will make you one that meets (most of) those requirements. It can be encapsulated in PVC or a Rollup - https://edsantennas.weebly.com

I have both a DBJ-1 (pvc) and DBJ-2 (rollup) and have no complaints.

I have 2 of the Ed Fong jpoles. One works ok. Other one is deaf.

Looks like he isn’t taking orders. I’ll look again in a few. Thanks!

Many articles and debates.
Here is a calculator that gives a good starting point.

I have one of these. Priced right. Shipped quick. Well packed. Works well on 2m and 440.

Jpole is problematic, ground dependent antenna. Go for GP.

gp - you mean ground plane? Or?
