I enjoy mixing my two hobbies, motorcycle and ham radio. 
The radio, on the table to the left, is the You Kit / Ten Tec R4020. The antenna is a 20 foot long 40 meter dipole only 7 feet in the air. 
Maybe you can say it's actually 2107 feet in the air. Hi Hi

For those that enjoy motorcycles, my bike is a 2002 Kawasaki ZRX 1200. I like to keep the R4020 and two antennas in the saddle bags
whenever I go for a bike ride. There are so many nice places to stop for a break and I always look to sit in the shade. It only takes about
5 minutes to string an antenna so I can relax, have a cold drink and make a few Q's.

Again, R4020 radio.
The mast clamped to the table is a 28 foot fiberglass telescopic flag pole. Attached to the top of it is an Off Center Fed 40 Meter antenna. Model number: OCF40QM. 
I used 35 feet of RG-174 to connect the radio to the antenna. Line losses are pretty low to use this coax on 20 and 40 meters. 











Everything I needed was packed on the motorcycle, including food and drinks. 
The telescopic flag pole is behind the blue foldable chair. Someone actually cut away the wooded seat on the picnic table so my chair
tucked perfectly in that spot. The 28 foot telescopic flag pole is only 42 inches long when collapsed. 














What do you do when there aren't any trees to hang an antenna from or a table to clamp the mast to? 

That's easy, fabricate a mount for a home brew multi band vertical, clamp it to the back of a foldable chair and add a few ground
radial wires. Just move the tap on the coil to change bands. I've worked a lot of DX with this antenna, two each 14 foot long
ground radials and only 5 watts CW. 
The radio is my KX3 with internal batteries and the Elecraft paddles attached to the bottom of the rig. I've since changed from the
Elecraft paddles to the Palm Pico Paddles. 


















Super easy to frabricate. A short length of angle aluminum, two each "U Bolts" and
an insulated 3/8" fine thread mount. 

You can use a Ham Stick, Hustler or almost any other mobile antenna. The one I made comes apart and fits in a 3" x 24" long lenght of PVC drainage
pipe with end caps. It can also be packed along with all of my other things when I go motorcycle portable. 


  





This is the complete vertical antenna assembly shown with a 3 inch diameter by 24 inch long PVC tube that is used to store and transport the package.
The PVC is nothing more the drainage pipe with end caps. The end cap on the right can be glued fast but I decided to use two tiny SS screws to hold the cap on. The other end of the PVC has a threaded PVC end cap for easy access. It is also held fast with two tiny SS screws. The reason I used SS screws to attach the caps was so I can change the length of the PVC tube if needed. 

Before I place the coil assembly in the storage tube I wrap it in bubble wrap. I want to protect the coil from any possible damage.
Since the total length of the tube is only 24 inches, it's easy to strap it to the motorcycle along with my foldable chair.  The length of the tube is dictated by the length of the telescopic whip and short mast. I can make the tube longer, but not shorter. There is access space inside of the tube so you can carry more radial wires if you choose to do so.

You will notice a "C clamp" and a strip of aluminum next to the clamp. Both are used so you can clamp the antenna to a table top. There is a BNC on the plate for attaching your coax and an SS machine screw for attaching ground radials.

Did you even see those green fiber glass military surplus 4 foot long tent poles for sale at a hamfest? That is what is shown above. If guyed properly you can actually make a nice 40 foot high mast using them.
I made a hinged base for the mast so it does not kick out while it is being erected. My grandson walked the mast up as I pulled on the nylon rope guys. I use three sets of a four point guy ropes. 

I use this mast to support an 80 meter off center fed antenna. This was used for the, "Go To Station", Kenwood TS 590S.

40 feet high with the OCF80 on top

Note: If you only use 8 of the four foot poles instead of using ten poles, you can erect the mast by yourself. You will also only need two guy points on the 30 foot mast.
