Discone Kav hlau txais xov

Nov yog kuv thawj zaug ntawm instructables.com, yog li kuv yog tus tshiab ntawm no, thov txim uas tsis tau ua tib zoo piav qhia cov kauj ruam kom raug. Ua lub kav hlau txais xov no nyuaj heev thiab nrhiav cov ntaub ntawv raug lossis zoo tshaj yog qhov nyuaj dua.

Muaj ntau lub laij lej kav hlau txais xov online tab sis kuv siv qhov no:

Kuv tau txwv los ntawm Aluminium pas nrig ntawm 99cm thiab xav tau txiav tawm cov khoom lag luam kos npe thiaj li xaus nrog 97cm kom pib nrog. Aluminium rods yog cov uas siv rau vuam.

1. Ob (2) tiaj Aluminium daim 6x6cm thiab txiav lawv mus rau hauv lub octagon los ntawm khij lawv cov npoo tom qab tilting lawv los ntawm 45 degrees.

2. Kaum ib (11) Aluminium Welding Rods 8 txiav rau 85 cm thiab 3 txiav rau 32 cm

3. PC (khoos phis tawj) lub rooj tsav xwm tseem ceeb-rooj yas yas spacers x 4

4. Peb (3) daim ntawm cov log tsheb sab hauv txiav tib qhov loj ib yam li aluminium octagons

5. TSO-239

6. Txog 10-20 Ntsia Hlau (nrog Ntsis ntsis ntsis)

7. PVC pas tuav lub kav hlau txais xov

8. Qee Daim Ntawv ntawm lub raj txiav ntawm 2 cm x 25 cm nrog lub qhov drilled ntawm txhua qhov kawg (los ua raws li phau ntawv qhia rau lub khob hliav qab)

9. Ib qho qhib 4x4 daim ntawm ib lub raj txhuas raj los ua tus tuav.

10. Ob (2) daim tiaj tiaj tiaj tiaj daim ntawm txog 3 x 10cm tuav lub kav hlau txais xov qhib lub thawv (saum toj #9) rau lub raj

Txiav daim ntawv octagons thiab muab lawv tso rau ntawm aluminium octagons, kos lawv nrog tus ntsia hlau thiab rauj (yog li laum me ntsis tsis plam thaum drilling). Kuv ntub daim ntawv nrog ATF-4 Kev xa cov roj kom yooj yim rau kev drilling.

Lub Kaum Hli 1 (DISC): Ua 8 qhov rau sab saum toj ntawm daim iav tsom iav thiab 4 qhov ntxiv rau PC Spacers thiab nruab nrab qhov txhawm rau txhawm rau xaim tooj liab rau lub disc.

Lub Kaum Hli 2 (Lub Cone): Zoo ib yam li tau hais los saum toj no hauv lub kaum hli ntuj 1, tab sis nthuav dav lub qhov nruab nrab kom ntxig rau SO-239 + 4 qhov ntxiv txhawm rau ntsaws lub qhov (socket).

Welded cov tsom iav ntawm Octagon 1 kab rov tav (txhaj rods @30cm) thiab Welded cov pas nrig rau Octagon 2 Ntsug (80 ++ cm).

(Yuam kev: qhov ntev hauv daim duab thib ob yog "cm" tsis yog "mm" (daim duab yog 1/10 nplai)

Muab cov hlau tooj liab tso rau nruab nrab nruab nrab rau SO-239

Nco ntsoov ntxiv cov rwb thaiv tsev li ntawm 1 cm lossis tsawg dua (Kuv siv 3 lub log log sab hauv uas ntxiv txog li 8mm tuab)

Txiav los ntawm cov roj hmab kom cia cov yas PC Spacers hla tau yooj yim thiab tom qab ntawd kaw lub hau sab saum toj nrog lub khob hauv qab nrog cov yas yas txuas. Thiab muaj tseeb qhov nruab nrab qhov nyias rau cov tooj liab hlau kom dhau

Muab cov hlau tooj liab tso rau sab saum toj (disc)

Ntsia cov kab hauv qab (Lub khob hliav qab) mus rau lub thawv Aluminium qhib (tuav) Raws li koj pom zoo tshaj plaws haum.

Tom qab sib dhos txhua ntu thiab ntsia lub thawv (hauv paus) rau cov tuav, koj yuav tsum tau ntxiv cov khoom thiab cov khoom ntawm cov raj txiav kom ze rau nruab nrab ntawm cov tsom iav (ntawm yuav luag 30 txog 40 cm ntsuas los ntawm sab saud). Qhov kev tsim no yog me ntsis flimsy thiab cov ntawv txiav yuav tuav lub khob hliav qab cuam tshuam los ntawm wobbling.

Txawm hais tias tsis tau npaj rau TX tab sis zoo li RX los siv nrog RTL-SDR dongle ua lub tshuab luam ntawv, tab sis txo hwj chim nws ua pov thawj kom muaj SWR 1.5 @ 140.000 Mhz thiab SWR 2.0 @ 150.000 Mhz.

Ib zaug ntxiv thov txim rau cov ntsiab lus uas ploj lawm.
