Small 2m Antenna?

[RHoy185]

Any Quarterwave antennas cover 136 to 174 MHz without being split up into smaller MHz increments? Would love to see a Laird 1/4 wave, under 24" on top of my truck that is able to pick up that range. Thanks in advance!

There are some broadband VHF antennas available; for receiving only there will be very little difference from one end of the band to anotehr if you select an antenna for about the mid-band point.

If you are only using it to monitor/receive, any 1/4 wave will do, i.e. approx. 19" will cover the range you want with little degradation related to frequencies above/below where it is exactly cut. Of course, if you intend to transmit, that is an entirely different matter.

I do plan on transmitting once I get my tech, which I have been putting off. I have been listening to local repeaters with my Icom R5 and would like to chime in once and awhile.

Here are two options that should cover your needs. I use one for 2 meter operation and it works great.
Field Tunable 136-512 MHz - HamCity / Ham Radio Equipment - HamCity / Ham Radio Equipment

Exactly what I am looking for, no description on the site but do you know how long the antenna is? Thank you for the link!

I am not sure if you give them a call they would probably know, I'm guessing 13-17" I have one tuned at 150MHz an dit works great from 136-174 and performs very well on 2 meters with a low swr

Here's what you do. Cut a quarter-wave antenna to slightly longer than 19.25 inches, which is the quarter-wavelength for 146 mHz, then prune it to the lowest SWR when it's on the vehicle, using either an SWR bridge or a wattmeter. That way you'll have the safest antenna for protecting your radio when you transmit and the best compromise for monitoring anywhere between 136 and 174 mHz.

The formula for figuring the quarter wavelength is (234/f in mHz) X 12.
