HF and VHF antennas from same mast?

[Nashua Area Radio Society]

I have a vhf/uhf vertical antenna mounted at top of an aluminum flagpole, feed line running down pole. Can I use same pole to Mount center point of a fan dipole and run its feed line also down the pole? Will that cause issues?

Thanks in advance. 73

I have a Diamond 200 on top of a 40 foot military aluminum pole with a 80M windom antenna below that, both with coax running down the poles. No issues seen so far after 2 years

Hello Russ,

There are no issues with running both feed lines down the mast.

The antennas have negligible coupling to the feed lines.

The fan dipole needs a balun so its feed line isn’t part of the antenna.  I’m assuming the U/V antenna has a ground plane

Hello Hamilton and James.

Thank you for your response and experience. The U/V arrived today, so hope to have it up this weekend (and yes, it does have ground plane). The dipole will take a bit longer since I’m being daring and building, but we’ll get there.

73.
