Setting Up an "R8 Cushcraft" Vertical Antenna

[@PY2NF]

Francesco, boa tarde. Você teve ótima idéia de fazer o suporte para colocar os tirantes. Parabéns. Ótimo vídeo. Muito bem ilustrado. 73. Francisco-PY2NF.

@QRPPPSK31 Hi Jack, tnx fer QTC. You welcome. If you have to setup an R8 remember: Set up/dwn stub for 6-10-12-15 m (i had to increase with a new stub +20cm the stub for 15m). Set up/dwn the connection under the 20m trap coil for 17m, not so long but you can move some cm. 20m - you can' t do nothing, only mods lenght of coil trap. 30m - you can cut or change the connection between the two traps (i had to cut 10 cm of alluminium tube for 30m SWR) 40m - tune the last stub on top of R8.

Complimenti un bel lavoro! IV3GNE

I have the R9 good antenna but Wonder what will happen to Cushcraft antennas now MFJ is winding down !!

[@sirhenry.overlander]

Great job. How is the R8 Crushcraft? Did it work until now? Do you have a draft from the construction? VY73 de DO1DPL

[@captain-Luca-is0hmz]

Ciao Francesco, personalmente ho sempre preferito non controventare le antenne per farle curvare con il vento ed evitare che si spezzino, tu hai trovato vantaggi? Io a breve monterò la R9 73

[@JCB12345]

Hello, I was facing problem with Cushcraft R9 on the 80 and 4om tuning. Hard to find proper point on the coil to place the tapping pin. I want to make 3.573 for the 80m and 7.074 on the 40m Loading coil. Meanwhile for another band I got better SWR. I was using RigExpert A55 Zoom. Dou have any advice or video for adjusting the taping?

Complimenti, ottimo lavoro, bellissima antenna! Bruno

@fasthandslow Just trying it since 08 July on all bands. Great antenna. If the location is open to the skyline you will not have any problems to work DX station. Have worked CX ZP PY in S.A., VK9H 40m in OC, JX EU. no problem very close, ST0 in AF, some trouble with VU direction because i have mountain, no prob with JA AS., caribean sea and so on. Runing an Icom IC-7700 with his output power ... 200 Watts, don' t use any amplifier. Stay tuned ... gl gdx 73 de IV3TMM.

[@fasnuf]

Wow. big job

[@iv3tmm]

@brubatt Le fascette a croce per gli occhielli dei controventi non sono isolate dai tubi in alluminio della R8 ... non interferiscono. L' importante è che gli occhielli del fili in teflon non tocchino i vari stub altrimenti andrebbero in corto con il tubo principale. Ciao 73 de IV3TMM.

[@iv3tmm]

@QRPPPSK31 Hope that you will set up a good antenna. Ciao Francesco. Stay tuned ... will be active as 9U3TMM at the end of the year.

[@bastyon75]

Nice job. I like it.

[@fasthandslow]

Hello, Great video, hopefully the R8 will be my next antenna. I’m very impressed with the guy wire support frame at the base of the antenna. How is the R8 performing on dx and what radio do you use? 73 de M3MQR

[@iv3tmm]

, but probably this way will change the 17m swr, be careful In this case you have to open the coil trap, it’ s a bit difficult but not impossible, good luck HI For 30m is the same way but in this case you can cut or alonge the tube between the two coils trap. In my case i cut 10centimeter the tube between the two coils trap. I suggest you to check very well the lenght of all alluminium tubes then tune ONLY 20m.

[@peteluetz2586]

Great video. Can you tell me about the guy wire base? IS this custom designed or is there a company or person who manufactures these? If not, are there drawings of the guy wire base design?

[@iv3tmm]

Pete Luetz It' s custom designed, send me your e-mail i will send you drawings. Ciao. IV3TMM

[@a45wh]

+Francesco Crosilla (IV3TMM) very nice pls send me the drawing to [e-mail] 73 san a45wh

[@xen6666]

+Francesco Crosilla (IV3TMM) Nice job! Please send me the drawing too. [e-mail]

[@Joe26003]

Nice work! Any chance you could share those drawings with me. I would appreciate it. email: [e-mail] Please put your call sign in the subject line.

[@johntaylor1244]

KJ4CGG I would also like drawing for the base of the R8 [e-mail] thanks John Taylor

[@brubatt]

ciao e complimenti volevo sapere cosa hai utilizzato per isolare le fascette dove hai attaccato i controventi 73 de bruno iw5ejp

[@antreasstathas16]

Vice job....besttttt

[@alphasxsignal]

Nice install

[@st8kout961]

While I'm no expert, I'm surprised you'd want a vertical, being so close to a hillside, unless that direction is not important. On the ground that looks like it would be a kid magnet. "Wow, lets go climb that pole."

[@alphasxsignal]

How is the antenna working for you? Do you have some videos of you using it on the air???

[@RichardAdkins]

Thank you so VERY much for sharing the design with us!!

[@captain-Luca-is0hmz]

A distanza di 6 anni.... raccontaci... Io avevo la R-9 purtroppo l'ho dovuta levare perchè non potendo mettere stralli oscillava parecchio e i vicini avevano paura, per il quieto vivere ho cambiato. A me ha regalato tante soddisfazioni

[@cd1168]

what is your location? is it italy?

[@iv3tmm]

After 20m swr is OK, then check again your swr on 30m and then tune 30m. Finally check again 40m swr and tune it. It ‘ s a long way but this is the ONLY RIGHT way to tune R8. I immagine that 6/10/12/15m swr is OK. Hope that you will tune your antenna. 73 de Francesco IV3TMM and tomorow on trip to Burundi operating as 9U3TMM for one week, stay tuned. Ciao.

[@SP9DLM]

hello :) I ask you, what is the length of the horizontal arm at the base of the mast extraction sp9dlm

[@iv3tmm]

Ciao, grazie del commento. Buona attività in radio, spero di collegarti. 73 de IV3TMM.

[@gianluigiviola1]

Ciao francesco, complimenti per l'eccellente tuning della R8, che spero di poter utilizzare anche con la mia antenna.Come ti dicevo prox volta che rientro da Mosca ci vediamo per chiarimenti.Ti ho inviato mia mail via SMS. A presto 73

[@iv3tmm]

PY2DS wrote Hello Francesco. My name is Murilo (py2ds), i bought a Cushcraft R8 in last mounth because i see your vídeo in youtube. Is a very good antenna but my SWR in 20 and especially in 30 meters is high. How i adjust the SWR in this bands? i wait your help. Grazie Murilo

[@RichardAdkins]

Where did you buy the Teflon guy cable? PLEASE!!! I can not find in the United States.

[@iv3tmm]

Richard Adkins you can find here: shop.irae2.com

[@RichardAdkins]

I am sorry, I can not find it on there. If you see it, would you please send me a link to that specific page? Thank you very much!

[@iv3tmm]

Give me you callsign on qrz dot com i will write to your email

[@iv3tmm]

Hi Murilo, first of all i thank you for watching my R8 movie then i can say you to tune your R8 antenna ... For 20m band there is no easy way to tune antenna because if: 1) your SWR down point is under 14.000 Mhz then it say that antenna is too long ! 2) your SWR down point is up 14.350 Mhz then it say that antenna is too short ! so to adjust antenna you have to: 1) cut internal coil trap 2) allonge internal coil trap or allone alluminium tube under 20m coil trap

[@fifino66]

Ciao Francesco, complimenti per l'installazione della tua Cushcraft......veramente impressionante la bontà del tuo lavoro.....Sono interessato all'acquisto della R9, (Cushcraft) e volevo chiederti un parere...... Ti ringrazio e 73 da IS0FGC Serafino

[@iv3tmm]

Ciao Serafino, mi dispiace la R9 non l' ho mai provata. Ho visto e letto solamente il manuale. Francamente, gli 80m super caricati ... non mi sembrano il massimo. Per il resto mi sembra uguale alla R8. Ciao de IV3TMM Francesco.

[@fifino66]

Ti ringrazio, gentilissimo!!!! 73 a te e famiglia e spero di ascoltarti on air!!!!

[@RichardAdkins]

drive.google.com/open?id=0BzHCj1HvwyywMTh4OXc5eVpLU1k The entire design of the antenna. It's in italian but, omg it is so invaluable. Grazie mille!!!

[@RichardAdkins]

I am duplicating your design for my R9 antenna. You have designed a wonderful system to stabilize the antenna. GENIUS!

[@emmausspy]

Bel lavoro . ....... però che musica di mer. .....sotto . Fa venire angoscia...🤪

[@mikec9537]

Interesting install, I'd like to hear you talk about, the music is useless.

[@cd1168]

i like the music..

[@epricedtechcom7621]

The best antenna build is useless if your cable connecting it to the radio is of bad quality.Select great components cables by reading these articles on how to select a good cable epricedtech.com/blog and see those unbelievable prices on Belden RG8X epricedtech.com/Coaxial-Cable-RG8X-RG-8X-Belden-7808A-50-ohm-Low-Loss-RF240-LMR240-LMR-240 and RG6 epricedtech.com/Belden-1694-A-rg6-coaxial-cable-f-connector-75-ohm

You don't know how to use words? To bad. Still shots and loud techno music are not helpful.
