The antenna will likely have a fine SWR on 440MHz (close to the third harmonic of 2m), so you could use it there. The radiation pattern is not the best on 440MHz, sending some radiation up at very high angles, but it will probably make some 440 contacts.

Making dual band (2m/70cm) antenna elements from welding

But note this will only help you for 2m, and should not be used on 70cm. For 70cm you can get a 70cm antenna, or perhaps find an antenna designed for both bands. This will add cost, however. For 70cm you can get a 70cm antenna, or perhaps find an antenna designed for both bands.

I am very satisfied with the performance of this 70cm antenna. Use the modelling program and make as directed. Will I make a 2 meter version of this ? Well I did. I wish to take part in the crossband sessions with VK3ASE (1863khz , top of your dial !) who accepts programme input on 145.3 Mhz and relays it on 147.475 Mhz. This is a difficult thing to do as no matter how hard you try to meddle

How does a Dual Band Handheld Antenna work? Amateur

Theoretically, this should provide an antenna gain of 3dBd at 2m. The antenna is dual banded to operate on 70cm using the same sleeve technique as used on the dual-band basic Flower Pot. This results in the antenna operating with four half-waves in phase on 70cm and provides a theoretical antenna …

Of course, to use the same thing for 70cm, or any other frequency over 2m, all I have to do is screw on another piece of tubing. In fact, all that needs to be done for 435MHz is to leave the antenna in place. The pattern is a bit toppy but will transmit OK if properly tuned for 145. (¼ wave for one, ¾ wave for the other ie. 145 x 3 = 435)
