I have a Tram 1481, 3 section fiberglass. When driven by an Anytone 5888, using a Telewave SWR meter, at 144.000, with 50 watts in, I show 1 watt reflected. At 462,750, the top of GMRS, I show 30 watts output and .2 watts reflected. A very wide banded antenna, price is very resonable. At 490.000m just to show band width, I still show 31 watts out and less than 1 watt reflected. This antenna would ewasily fill what you are looking for.

So from what I read, you are using this on GMRS as well as Ham frequencies?

In response to the Arrow OSJ antenna.
I built one of these antennas using very careful measurements
and taking my time to get everything as close to perfect as possible.
On the elements, I tapped the tops of the 3/8" rod with threads for about
2". I put a 3/8" coupler on that with a lock nut. That is how I adjust the SWR.
The coupler can now extend the element by turning it up or down. Then lock it
in with a 3/8" nut.

While NOT the best antenna, it still works. My latest one only has only the 2
elements because it is strictly for GMRS use and not 2 meter. Good luck

What are you using for coax?
