Common Questions from Customers:

How do I tune-up the Greyline Antennas on the bands?

We work with lots of 'new to ham radio' customers so this is an important review. We do keep it simple and by no means does that mean entry-level antenna or results.

First, assuming your antenna system is built properly (you followed directions), the coax is of good quality back to the shack, and you're using a relatively modern radio and remote tuner, let's agree everything is working as it should and begin:

1. Let's be sure all the gear is on and connected properly.
2. Lower power to 20 Watts or so for this first tune cycle
3. Set the display to showcase SWR
4. Go to the frequency you wish to operate
5. Put the radio in AM mode (or FM)
6. Find the "Transmit" button and press it
7. Allow the remote tuner to run it's tuning cycle until finished
8. Turn the power back up to your desired output power
9. Select your intended Mode of operation
9. Tune the bands and have fun!

Pro Tip: Be certain you're feeding the top, longer vertical radiator! Check to be sure the internal conductor within your coax is connected to the longer, upper section of your Greyline antenna. This may add 25-35 dB to your signal. Otherwise you are using the lower portion of your antenna and, well, that's lower. Imagine if you've been working DX with the lower four feet of the antenna and discover this bonus? It's happened more than once :-)


What is the difference between the Greyline HF Vertical Dipoles & Flagpole Antennas?

Graphic: Performance difference between the antennas: Looking carefully at the graph for the angle of signal and antenna gain comparisons you'll notice incremental increases in depth of signal penetration, on the lower bands mainly. 

Key: *80M-red | 40M-blue | 20M-green | 15M-orange

See that? Even the 12' vertical antenna holds its own, on 80M. Notice the 20 and 28' has an even lower angle and punch for deeper DX performance. (to plot the 24' you can simply imagine it's between the 20' and 28' and be very close.)

Customers report working 160M with the 16' DX Flagpole. That's great news!


How to choose your Greyline HF Vertical or HOA Flagpole Antenna?

We wrote about that, here. Let's be sure you are choosing the correct antenna system for your needs. Most folks will see little difference between 20' and 24'. The extra 4' in this case makes life much easier for your matching network on 80-160M.

Do I need a Tuner at the Base of the Vertical or can I use desktop or shack tuner?

Many folks use their tuner in the shack. At low power and a reasonably short coaxial runs, losses may be overlooked. We do believe strongly the tuner at the antenna is the best way to keep efficiency at the highest levels.

Rig ATU: the tuner inside your radio is likely not strong enough to tune (impedance range) a multi-band antenna on more than a couple of the bands. These rig tuners are meant to resolve a rather small mismatch. As the Greyline OCF HF antennas are designed as a non-resonant antennas they therefore require a quality matching network to achieve the high efficiency we wish for you to enjoy across 160-6M. Does the exact same job as the unsightly stubs, coils, traps, etc., only prettier.

Desktop ATU: Most desktop tuners on the market will do the job easily from 160-6M and this is a very popular method that works loads of DX and passes important traffic, we are sure of that. Please know, the tuner at the vertical is the very best, lowest loss option that we offer to feed your antenna system.

Remote Tuners: The advent of remote tuners that can be installed at the antenna has been a benefit to our antenna systems for the Amateur Radio enthusiast. They are cost effective and work well for the needed job. Each we recommend indeed work well to tune the vertical radiator to every frequency you may desire. Some are better than others too. Look closely at the power ratings and impedance range to ascertain the level of quality your selection may offer against your bands and modes of operation. In any case, all of the remote tuners on our website do the job nicely and you'll be very pleased at how easily they match up together.
